Nevada experiments with ‘biochar‘ to improve health of forests

1 January, 2016

CARSON CITY — State land stewards are experimenting with an ancient method to improve the health of Nevada forests and make use of the renewable resource — baking tree trunks and limbs in a slow cooker to turn them into charcoal.The technique is as old as the ages and was commonly used by Nevada pioneers and early miners to create an energy source for warmth and smelting.Today there is a new focus: using “biochar” to improve soil nutrients and water retention.Eric Roussel, a biomass and seed bank coordinator with the Nevada Division of Forestry, has been toying with the idea for several years.”The idea really came out of pinyon and juniper utilization,” Roussel said. “We’re having tremendous issues with pinyon and juniper in terms of forest health and fire fuel.”Pinyon and juniper forests across Nevada’s many mountain ranges have been left largely untended, making them more susceptible to devastating wildfires, disease and insect infestations.”We’re seeing this great woodland going away,” Roussel said. “One of the ways we treat these problems is having a value on the forest.”Juniper trees were commonly used in the West for fence posts, until metal T-posts came along and shut down the post industry, he said.”We were left with the forest that doesn’t have some tremendous marketable use … besides pine nuts and firewood,” he said.Roussel began researching ways the forest was used historically. Charcoal production was one of them. One prime example in Nevada is the Ward Ovens south of Ely.The six beehive-shaped ovens, which were built and used in the 1870s, stand 30 feet tall. The ovens could burn 35 cords of wood at a time and produce about 1,000 bushels of charcoal that was used in the mining process. The site is now a state park.Opportunity knocksThe latest project took shape about four years ago when the U.S. Forest Service began cutting down pinyon and juniper trees in an area near Ely because they were encroaching into critical sagebrush habitat.That’s when state forestry officials decided to experiment with reviving the method of turning trees into charcoal or biochar.”It’s called charcoal when you use it for energy.

Nevada experiments with ‘biochar‘ to enhance health of forests

1 January, 2016

“It basically works just like a sponge,” he stated, “so we are in a position to retain lots of water that will otherwise evaporate or undertake the soil really rapidly.”

“We are mixing it within our compost at approximately a ten percent rate,” Getty stated because he rattled and shook off several advantages of biochar-overflowing soils. The compost can be obtained in your area in Northern Nevada, but Getty stated he’s searching for marketers in Southern Nevada to hold his product.

And adding biochar to compost saves irrigation water, he stated, observing it may hold five to 10 occasions the weight in water.

The strategy is really as old because the age range and it was generally utilized by Nevada pioneers and early miners to produce an power source for warmth and smelting.

After that, it is all about manipulating the burn. Burn it too quickly, and also the wood turns to ash. The secret would be to keep oxygen levels low. When the fire is burning hot, vents are closed off and sealed to permit the wood to simmer gradually.

Creating a commercial marketplace for biochar is essential to the prosperity of your time and effort, Roussel stated.

“You want to find methods to make use of the forest, encourage management, offset a few of the costs making the forest much healthier and sustainable,” he stated.

Pinyon and juniper forests across Nevada’s many mountain ranges happen to be left largely untended, which makes them weaker to devastating wildfires, disease and bug contaminations.

Experiments are now being done around the open range. Biochar has been spread on test plots, alongside regions of without treatment ground, to record any variations in soil conditions and plant growth.

It takes approximately two hrs to load the wood. Inmate work deck hands assist with the labor.

“The concept really arrived on the scene of pinyon and juniper utilization,” Roussel stated. “We are getting tremendous difficulties with pinyon and juniper when it comes to forest health insurance and fire fuel.”

With funding in the Eastern Nevada Landscape Coalition and also the Forest Service, the condition agency presently has 10 portable ovens, or kilns. Each measures 8 ft tall and eight ft wide and may convert about 1,200 pounds of tree material into 600 pounds of biochar.

Biochar is very porous. Due to its spaces and crannies, one handful might have comparable area being an entire footfall area, Roussel stated. And all sorts of individuals cracks holds lots of water.

“That’s truly the benchmark for all of us, when private industry sees there is a marketable product here,” he stated.

“We wound up with the forest that does not possess some tremendous marketable use … besides pine nuts and fire wood,” he stated.

He’s excited for an additional reason.

Chance knocks

The cooking process takes about 24 hrs. It requires a later date for that biochar to awesome off.

Roussel started researching ways the forest was utilized in the past. Charcoal production was one of these. One prime example in Nevada may be the Ward Ovens south of Ely.

“We are seeing this excellent woodland disappearing,Inch Roussel stated. “One way we treat these complaints is getting something around the forest.”

“We obtain 10 of these going at any given time,Inch Roussel stated.

Nevada Division of Forestry along with other researchers are experimentation with methods to make biochar in a commercial sense viable. To date, Roussel stated, the prospects look promising not just for backyard home gardeners however for rangeland management and pollution control.

This is when condition forestry authorities made the decision to test out refreshing the technique of turning trees into charcoal or biochar.

Eric Roussel, a biomass and seed bank coordinator using the Nevada Division of Forestry, continues to be toying using the idea for quite some time.

“We’re composting it and adding it to agriculture land to find out if zinc heightens yield,” Roussel stated.

The six beehive-formed ovens, that have been built and utilized in the 1870s, stand 30 ft tall. The ovens could burn 35 cords of wood at any given time and convey about 1,000 bushels of charcoal which was utilized in the mining process. The website has become a condition park.

“It’s known as charcoal if you use it for energy. However when you apply it soil amendment it’s known as biochar,” Roussel stated.

Commercial programs

Juniper trees were generally used in the western world for fence posts, until metal T-posts arrived and shut lower the publish industry, he stated.

Compost without biochar normally lasts 3 to 5 years, he stated. By comparison, he pointed towards the wealthy soils from the Amazon . com.

Dink Getty, who owns Great Basin Organics and Genoa Trees in Douglas County’s Carson Valley, continues to be following developments in biochar for around 3 years. But he’s already a large believer, a lot to ensure that he started making their own biochar previously year.

The most recent project required shape four years back once the U.S. Forest Service started reducing pinyon and juniper trees within an area near Ely simply because they were encroaching into critical sagebrush habitat.

“It is a great concept,” Getty stated. “Biochar isn’t anything really a new comer to research. There’s lots of data. It simply has not been utilized in the wood industry so far as attempting to make use of all this wasted wood in Nevada.”

He’s a lasting kiln that may produce three to five a lot of biochar weekly. He makes use of slash piles remaining from forest loss projects close to the Lake tahoe Basin and grindings in the nearby Bently Ranch, which accepts eco-friendly waste in the community because of its own composting operation.

“For me personally the neatest factor may be the tie as to the we did in the past,” Roussel stated. “Exactly what a awesome method to make use of an old solution for any new problem.”

What it is used

“We’ve more pinyon and juniper acres than we have ever been on Nevada,” Roussel stated. “This may be a method to keep your forest healthy and productive.”

Today there’s a brand new focus: using “biochar” to enhance soil nutrition and bloating.

CARSON CITY — Condition land stewards are experimentation by having an ancient approach to improve the healthiness of Nevada forests and take advantage from the renewable resource — baking tree trunks and braches inside a crock pot to using them as charcoal.

“People made it happen within the 1500s … which soil continues to be black and fertile,” Getty stated.

Biochar has been combined with other compost materials to be used at condition plant centers. Besides holding water, biochar adds nutrition to soil, aiding plant growth.

In November and December, deck hands made about 70 cubic yards of biochar.

Creating ‘biochar’

Another possible me is storm water treatment. Just like charcoal filters clean harmful particles from seafood tanks and pools, Roussel stated, biochar might find use like a soap for storm water runoff.

“We’re seeing this great woodland going away,” Roussel said. “One of the ways we treat these problems is having a value on the forest.”

That’s when state forestry officials decided to experiment with reviving the method of turning trees into charcoal or biochar.

“It’s called charcoal when you use it for energy. But when you use it for soil amendment it’s called biochar,” Roussel said.

“We want to find ways to utilize the forest, encourage management, offset some of the costs and make the forest more healthy and sustainable,” he said.

Creating ‘biochar’

With funding from the Eastern Nevada Landscape Coalition and the Forest Service, the state agency now has 10 portable ovens, or kilns. Each measures 8 feet tall and 8 feet wide and can convert about 1,200 pounds of tree material into 600 pounds of biochar.

How it’s used

Nevada Division of Forestry and other scientists are experimenting with ways to make biochar commercially viable. So far, Roussel said, the prospects look promising not only for backyard gardeners but for rangeland management and pollution control.

Biochar is extremely porous. Because of all its nooks and crannies, one handful can have about the same surface area as an entire footfall field, Roussel said. And all those crevices can hold a lot of water.

“It essentially works like a sponge,” he said, “so we’re able to retain a lot of water that would otherwise evaporate or move through the soil really quickly.”

Another possible use is storm water treatment. Just as charcoal filters clean impurities from fish tanks and swimming pools, Roussel said, biochar may find use as a cleaning agent for storm water runoff.

Commercial applications

Dink Getty, owner of Great Basin Organics and Genoa Trees in Douglas County’s Carson Valley, has been following developments in biochar for about three years. But he’s already a big believer, so much so that he began making his own biochar in the past year.

He has a permanent kiln that can produce 3 to 5 tons of biochar weekly. He uses slash piles left over from forest thinning projects near the Tahoe Basin and grindings from the nearby Bently Ranch, which accepts green waste from the community for its own composting operation.

“We’re mixing it in our compost at about a 10 percent rate,” Getty said as he rattled off several benefits of biochar-enriched soils. The compost is available locally in Northern Nevada, but Getty said he is looking for distributors in Southern Nevada to carry his product.

Compost without biochar normally lasts three to five years, he said. By contrast, he pointed to the rich soils of the Amazon.

“People did it in the 1500s … and that soil is still black and fertile,” Getty said.

And adding biochar to compost saves irrigation water, he said, noting it can hold five to 10 times its weight in water.

“It’s a great concept,” Getty said. “Biochar is not anything really new to research. There’s a lot of data. It just hasn’t been used in the wood industry as far as trying to use all this wasted wood in Nevada.”

Developing a commercial market for biochar is key to the success of the effort, Roussel said.

“That’s really the benchmark for us, when private industry sees there’s a marketable product here,” he said.

“We have more pinyon and juniper acres than we ever had in Nevada,” Roussel said. “This could be a way to keep the forest healthy and productive.”

Uncommon Good

2 January, 2016

This is a very nice article about a group in the Claremont area called Uncommon Good:

 

Uncommon Good uses biochar and other amendments for locally grown organic produce. To quote their website (http://uncommongood.org/?page_id=160): 

 

“Half of the food grown is sold to the community from Uncommon Good’s office, Monday through Saturday. The other half is given to the families served by Uncommon Good who cannot afford fresh produce. The farmers are fathers of children in the education program who are paid a living wage and benefits by Uncommon Good. The farm plots also serve as real world learning laboratories, both for science subjects and small business development skills, for the students and parents served by Uncommon Good.”

I was recently given a large amount of biochar, I’m not sure what would be better, incorporating it into the soil or using it as a mulch. If I used biochar as a mulch, would it hold the nutrients from the compost teas and release them slowly with each watering? Or would the soil microbes benifit more with it being in the soil?

During soil fumigation, it is ideal to mitigate soil fumigant emissions, ensure pest control efficacy, and speed up the recovery of the soil microorganism population established post-application. However, there is currently no fumigant emission reduction strategy that can meet all these requirements. In the present study, replicated soil columns were used to study the effect of biochar derived from rice husk (BR) and green waste (BG) applied to the soil surface on 1,3-dichloropropene (1,3-D) and chloropicrin (CP) emissions and soil gas distribution, and on microorganism population re-establishment. Relative to fumigated bare soil (no emission reduction strategy), high density polyethylene (HDPE) and ammonium thiosulfate (ATS) treatments, BR gave dramatic emission reductions for both fumigants with no obvious emission peak, whereas BG was very effective only for 1, 3-D. With BR application, the concentration of fumigant in the soil gas was higher than in the bare soil and ATS treatment. After the soil column experiment, mixing the BR with the fumigated soil resulted in higher soil respiration rates than were observed for HDPE and ATS treatments. Therefore, biochar amendment to the soil surface may be an effective strategy for fumigant emission reduction and the recovery of soil microorganism populations established post-application.

Nevada experiments with ‘biochar‘ to improve health of forests

Delhi can deal with pollution

Delhi has become the most air polluted city in the world. Urgent and effective actions are needed to bring the pollution level down. The cost to the health of Delhi citizens far exceeds any cost that some may have to bear to reduce it. Cleaning up Delhi’s air will require technical, managerial and organisational efforts and will take time.

Still, steps should be taken to provide some immediate relief. The odd-even policy is a good beginning. While the reduction in total emissions may be small, the marginal impact on health would not be negligible as the impact on health increases non-linearly with the level of pollution. This needs to be followed up with a comprehensive strategy.

The sources of air pollution in Delhi are many: About three million trucks and cars, particularly diesel-driven, and five million two-wheelers, tens of thousands of trucks many of which just go through for want of a bypass, road dust, burning of biomass, industry and power plants, construction dust and in October-November, burning of paddy stubbles in Haryana and Punjab. The relative contribution of these vary from season to season and for pollutant to pollutant.

For example, the contribution of transport to PM 2.5 (particulate matter of size less than 2.5 microns) is estimated to vary from 25 to 60 per cent.

How do we deal with all the sources of pollution and clean up Delhi’s air in reasonable time? The measures are well-known, but we indicate how to implement them effectively. Car-use on alternate days is a measure that can be immediately implemented. How much impact it will make is difficult to estimate as a number of exemptions have been given. But surely, it will have some immediate impact. Over time, people may buy another cheaper, and more polluting, car. But that will take time. Meanwhile, if public transport is improved, more people might get accustomed to using it or get into the habit of sharing cars.

Questions are raised about the implementation of the odd-even policy. This is not difficult to implement. Install cameras at major junctions and fine those who violate it based on the visuals. The fines may increase steeply with repeated violations. Alternatively, select a few locations every day on a random basis and impose very large fines on violators. For example, in Vienna, tickets on public transport are not checked. But once in a blue moon, there is checking and the fine imposed is equal to more than one year’s free rides.

How much impact on air quality can the odd-even policy have? In 2001, when Delhi buses and taxis moved to CNG, we saw significant improvement in air quality. The odd-even numbered car policy should produce a visible impact.

However, this experiment should be over a longer period than 15 days. Also, intensive measuring of air quality in
different parts of the city should be done even after the fortnight experiment is over to have a good understanding of its impact.

Of course, loopholes in the policy should be removed. Two-wheelers should also be included once the number of buses in Delhi is increased, which should be done in a few months at most.

Building a bypass had been pending for years, although the work has now begun. It will take a year or two to be completed. Meanwhile, restricting the entry of trucks to the city for late night hours can give some relief. The measure to restrict entry till 11pm is a good one. As the trucks will move faster, it should reduce emissions. This would have some immediate impact.

To promote walking and cycling, the city requires footpaths and cycle paths. Footpaths must be levelled and should not require getting off and on at every gate: Cars should go up and down, not people. Footpaths should not be encroached upon by hawkers who may be provided alternate space. If constructing footpaths and cycle tracks requires that one car lane has to be reduced, that should be done. All citizens should have equal rights to road space.
This may take a year or two. The work must start soon.

Implementing Euro 6 norms should not wait. While refineries will have to make substantial investments to produce clean fuels, it is unavoidable and should not be postponed. In any case, it will increase the price of diesel by about one rupee per litre. Surely, this can be borne by diesel-vehicle users. Also, instead of a one-time tax on diesel vehicles, the difference between diesel and petrol prices should be narrowed and an annual tax on diesel vehicles should be imposed. Euro 6 does not have to be implemented all at once for the whole country. One can
begin with metros and larger cities. This may not be 100 per cent effective, but largely so.

Automobile manufacturers should be required to produce Euro 6-compliant vehicles no later than 2018. From January 1, 2018, registration and sale should be banned of vehicles not meeting Euro 6 norms. Import of Euro 6 vehicles with a certain fuel efficiency norm should be encouraged to provide incentives to domestic manufacturers.

For controlling road dust, vacuum cleaning of roads can be done. This can be accomplished within three to six months.

Paddy stubble burning in Punjab and Haryana is attractive to farmers as it takes less labour, controls pests and is quick. However, the paddy loses nutrients. A better way would be to remove the stubble and burn it with little or no oxygen to produce bio-char, which is then applied to the land. This is practised in the Phillipines. Biochar
improves the fertility of the soil and reduces carbon dioxide emissions when compared to burning. However, it requires more labour. A mechanism can be developed whereby farmers are compensated for the extra labour through carbon certificates. For example, a private firm can finance farmers to produce biochar and get carbon certificates.

Thus, Delhi can have clean air within two years if all the measures suggested here are implemented. The Aam Aadmi Party’s strategy is a good one for some immediate relief. However, it must initiate action on all the other measures now.

Integration of biochar and chemical fertilizer to enhance quality of soil and wheat crop

7 January, 2016

A wide variety of soil amendments like manures, compost, humic acid and bio-sorbents have been used to make nutrients available to crops as well as to protect them from toxic elements. Among soil amendments, biochar has been known to improve soil crumping, soil nutrients’ availability to plants and ultimately the yield of crops. A field experiment was conducted by using biochar prepared from Dalbergia sissoo Roxb. wood by brick batch process. Two doses of biochar were applied to soil 0 and 12 t ha-1. Fertilizer rates used in the experiments were 25% recommended doses of fertilizers (RDF), 50% RDF, 75% RDF and 100% RDF alone & with biochar applied under two factorial randomized complete block design in natural field conditions (RDF of NPK fertilizer is 120-60-60 kg ha-1) . Soil physico-chemical properties viz., bulk density, particle density, porosity, pH, electrical conductivity, organic matter, soil organic carbon, total nitrogen, available phosphorus, available potassium, soil organic carbon, soil microbial biomass carbon and soil microbial biomass nitrogen were measured from the soil samples collected from 0-30 cm depth. All these parameters varied significantly among the treatments. A combined treatment of biochar and 50% of the recommended dose of NPK was most effective for soil conditioning. Agronomic parameters were also measured by standard methods. Due to chelation of heavy metal ions and availability of nutrients to the soil, yield of the crop may significantly increase due to cumulative treatment of fertilizer and biochar but upto a certain limit.

Abstract

Bio-oil and bio-char were produced from potato peel waste (PPW) and PPW fermentation residue (PPW-FR) using a laboratory-scale auger pyrolyzer at 450 °C. Proximate and ultimate analyses of the feedstock materials PPW and PPW-FR were determined. The bio-oils were fractionated and analyzed by gas chromatography mass spectrometry (GC-MS), high-performance liquid chromatography (HPLC), and electrospray ionization mass spectrometry (ESI-MS). The bio-chars were characterized by Fourier transform infrared spectroscopy (FTIR) and butane activity (BA) measurement. The PPW and PPW-FR bio-oils had a relatively high level of lipid and suberin-derived compounds as compared with hybrid poplar (HP) pyrolysis bio-oil. The BA measurement also suggested that PPW and PPW-FR bio-chars have better adsorption performances than HP bio-char.

Abstract:

Biochar’s role on greenhouse gas emission and plant growth has been well addressed. However, therehave been few studies on changes in soil microbial community and activities with biochar soil amend-ment (BSA) in croplands. In a field experiment, biochar was amended at rates of 0, 20 and 40 t ha−1(C0, C1and C2, respectively) in May 2010 before rice transplantation in a rice paddy from Sichuan, China. Topsoil(0–15 cm) was collected from the rice paddy while rice harvest in late October 2011. Soil physico-chemicalproperties and microbial biomass carbon (MBC) and nitrogen (MBN) as well as selected soil enzyme activ-ities were determined. Based on 16S rRNA and 18S rRNA gene, bacterial and fungal community structureand abundance were characterized using terminal-restriction fragment length polymorphism (T-RFLP)combined with clone library analysis, denaturing gradient gel electrophoresis (DGGE) and quantitativereal-time PCR assay (qPCR). Contents of SOC and total N and soil pH were increased but bulk densitydecreased significantly. While no changes in MBC and MBN, gene copy numbers of bacterial 16S rRNAwas shown significantly increased by 28% and 64% and that of fungal 18S rRNA significantly decreased by35% and 46% under BSA at 20 and 40 t ha−1respectively over control. Moreover, there was a significantdecrease by 70% in abundance of Methylophilaceae and of Hydrogenophilaceae with an increase by 45% inAnaerolineae abundance under BSA at 40 t ha−1over control. Whereas, using sequencing DGGE bands offungal 18S rRNA gene, some bands affiliated with Ascomycota and Glomeromycota were shown inhibitedby BSA at rate of 40 t ha−1. Significant increases in activities of dehydrogenase, alkaline phosphataseswhile decreased -glucosidase were also observed under BSA. The results here indicated a shift towarda bacterial dominated microbial community in the rice paddy with BSA.

Biochar is an organic soil amendment currently being researched and used in a variety of applications across Colorado. Biochar has the potential to provide benefits to multiple economic sectors integrated within its supply chain, for example biochar and biofuel co-production can provide additional revenue streams for forestry and waste management. Biochar applications may have a critical role in mitigating climate change, reclaiming and restoring land, and boosting soil fertility for agriculture and horticulture. This article explores some of the latest research relevant to biochar applications in Colorado such as:

Biochar is charred organic matter used deliberately as a soil amendment, with the intent to improve soil properties1. Biochar is made by heating biomass to high temperatures (480-1800°F) in the absence of oxygen through pyrolysis2. Pyrolysis chemically and physically alters the composition of the biomass producing a highly porous, stable form of organic matter that can be used as a soil amendment. Biochar can be produced from a variety of feedstocks including forest residues, agricultural residues, waste, and purpose grown biomass. The source material and the pyrolysis conditions are major controls on the biochar’s pH, ash content, elemental composition and stability. Therefore, both the biochar feedstock and production conditions can have important implications on how biochar amendments influence soil properties and their efficacy for different management objectives.

If biochar production can be accomplished in a cost effective manner, it may change how forests are managed. Specifically, trees that are killed by pests, such as mountain pine beetle, may be viewed as a productive source for manufacturing biochar, rather than a wasted resource. At this writing, Colorado’s forests suffer from overcrowding due to wildfire suppression and massive losses from recent pest outbreaks3. Current forest management practices involve controlled burning and harvesting and burning in smaller slash piles.

These practices are expensive, pose fire risks, cause smoke pollution, and can degrade the land if not properly managed. Biochar production has potential to turn beetle-damaged stands, hazard trees and other residues from fuels reduction treatments into value-added product. Rather than being burned, the trees and residues would be harvested as a feedstock. Preliminary results demonstrate that there may be support among Colorado residents for this type of management program. A recent study of Colorado households indicated that residents were hypothetically willing to pay roughly the same for burning slash on-site and moving it off-site for biochar production as a means of reducing the intensity of future wildfires4.

Biochar companies in Colorado are producing woody biochar on a small-scale, experimental basis from forest stewardship contracts with the USFS and residues at pelleting operations. If woody biochar is found to be an effective soil amendment, then there will likely be an increase in demand. Biochar production would thus provide additional value by helping to lower the cost of forest management practices. While there is promise for market development, the effectiveness of using pine-based biochar as a soil amendment needs to be better documented. Preliminary studies also indicate that long distances between the forest and the biochar processing centers should prompt a closer look at pre-processing or other means for reducing transportation costs associated with making biochar from pine beetle killed wood5,6.

Biochar producers can also optimize the operating conditions to produce gas (syngas) and liquids (bio-oil) in addition to the solid biochar residues. The gas and liquid fraction can then be upgraded to produce biofuel. These systems typically apply fast pyrolysis, using moderate pyrolysis temperatures (~950°F) and shorter residence times, to optimize for bio-oil production and gasification, using higher temperatures (~1,650°F) and moderate residence times, to optimize syngas production(2). Studies have found that biochars produced under higher temperatures tend to have more stable compounds, higher ash content and increased porosity leading to more persistent biochar with higher sorption capacity7. In a recent industry survey the International Biochar Initiative found that 12% of respondents were pursuing syngas production as a by-product of biochar production and 7% were working towards collecting and refining bio-oils8. While none of the commercial biochar facilities in Colorado currently co-generate biofuels there are some companies working on scaling up such technologies. Recent biochar and bio-energy co-production studies show that co-production may reduce overall waste and carbon footprints(6). However, at this writing, biochar and bio-energy co-generation is generally not an economically viable venture unless a monetary value is assigned to carbon dioxide emissions5,9. Some bioenergy and biochar production has been shown to be economically feasible on a case-by-case basis(10)(11). Product selling price uncertainty contributes to risk of private investment into a biofuel production facility(12).

Biochar has recently gained much attention as a way to capture carbon from the atmosphere and mitigate global climate change. Plants naturally convert atmospheric CO2 into biomass which then gets recycled back to the atmosphere through respiration, burning or decomposition. In natural systems 80-90% of the carbon in biomass returns to the atmosphere after a few years to decades from decomposition in the soil. Likewise, after a natural fire, it is estimated that up to 25% of the carbon in the burned biomass is converted in more stable forms of organic matter like biochar(13). Pyrolysis of organic matter under controlled conditions can significantly increase the retention of carbon with 10 to 50% of the original biomass carbon retained depending on the conversion process3.

A study looking at the stability of multiple types of biochar showed biochar had a mean residence time ranging from 90 to 1,600 years14. Similarly, in a two year lab study at Colorado State University (CSU), wood-derived biochar amended to four soil types primarily remained in the soil, yet a small fraction of it (<3.2%) was consumed by the soil microbes(15). In the soils with an organic carbon content larger than 1.97%, the biochar applications lead to increased soil respiration with the biochar possibly providing a shorter-term carbon source15. Therefore it is important to continue to study the stability of biochar using long-term field experiments to better understand the biochar’s full carbon sequestration potential.

Research shows biochar can also reduce emissions from more potent greenhouse gasses such as nitrous oxide (N2O). A recent review of 56 studies found that biochar has been shown to decrease N2O emission by 49%16. Researchers have looked at a variety of mechanism by which biochar could reduce N2O emissions including reducing the amount of nitrogen available for transformation into N2O, altering the soil conditions most favorable to N2O production and generating conditions that more efficiently convert N2O to N2 gas. CSU is currently conducting lab incubations and field experiments to better understand the mechanisms by which biochar impacts nitrogen cycling and decreases N2O emissions from fertilizer. This work can help inform how biochar can be applied to reduce greenhouse gas emissions and manage nitrogen cycling in soils.

Certain biochars have also been shown to have high sorption capacity which could be used to immobilize contaminants in soil. Biochar with small particle sizes and high surface area have also been shown to sorb organic pollutants(7). Biochar’s high pH can also help provide a liming effect for reclamation of highly acidic soils. A study by the USGS on two hardrock mine tailing sites, where soils are subject to metal toxicity and high acidity, found that the addition of biochar had differing effects across sites(17). At one site, biochar amendments decreased the leaching of aluminum, cadmium, copper, lead and zinc. However, at the other site, biochar addition increased the mobilization of copper and zinc. The study also found that higher application rates may be necessary to sufficiently raise pH and reduce toxicity. Therefore, biochar addition can potentially provide a low-cost alternative for reclamation of soils contaminated with heavy metals, organic pollutants or high acidity but requires careful consideration of site-specific properties beforehand. There is considerable opportunity for mining companies or other private sector companies to earn a profit by investing into the development of biochar technologies that are specific to mine site remediation18.

Biochar is also being explored for its potential to aid in ecological restoration of degraded soils to help build soil organic matter, facilitate plant regeneration and provide preferential habitat for soil microbes and biota. The USFS and CSU are currently collaborating on a project exploring biochar’s ability to aid in carbon sequestration, nutrient retention and revegetation of decommissioned forest roads in the Arapahoe National Forest.

In a series of qualitative research interviews conducted in 2011 with biochar purchasers and home/ garden supply stores, the majority of biochar in Colorado was sold for mine reclamation applications and experimental forest research conducted by government agencies and entrepreneurs. Pine wood chips comprised the typical feedstock, and the average order was approximately 6,400 lbs, or on the order of 25 to 30 cubic yards depending on the density of the specific biochar18.

Biochar has many properties that have potential to enhance soil fertility. Biochar constitutes a highly stable form of soil organic matter. Soil organic matter is important in retaining water, regulating the exchange of nutrients, and building soil structure through aggregation. Biochar additions may have the ability to increase the water holding capacity of soils by adding additional pore space and supporting aggregation. However, studies have also looked at how biochar may increase infiltration of water through soils so there may be a tradeoff19. Research is currently underway at CSU to explore biochar’s impact on soil moisture across different irrigation treatments. Other regions are also looking at the application of biochar to provide a liming effect in more acidic soils or help mitigate nitrate leaching in regions with higher precipitation.

Biochar can also play an important role in higher valued crop systems like orchards or gardens where the economics are more favorable. Biochar producers have worked in turfgrass management, vineyards, and are looking at opportunities in the emerging cannabis industry in Colorado. Biochar has been considered as a growth medium, a soil inoculum or an organic matter source. With its stable structure, biochar does not always offer many nutrient inputs to the soil, although some manure-based biochars have been shown to add nitrogen to soil. However, biochar’s sorption properties can play a key role in retaining nutrients(20). Many producers offer biochar blends mixed with other organic fertilizers to deliver a slower release of nutrient over time.

A small commercial biochar market has developed in Colorado and biochar is being applied to meet a diverse range of management objectives. The biochar literature is rapidly expanding and many studies have shown the effects of various biochar treatments. We must continue this research to examine the mechanisms controlling these effects which will allow us to better inform management practices. Biochar’s impacts on soils are not universal and must be tailored to suit the given management goals. As the research and applications continue to develop, scientists, entrepreneurs and land managers will all play a critical role in determining the opportunities for biochar in Colorado.

Should you have the inclination, you could experiment with biochar in your own garden to assess the performance in Colorado soils. The section below contains information for finding biochar producers. Look for more information on biochar as it becomes available from research projects across the state.

Biochar Trial Update, Charging Biochar & a Rock Dust Field Trial?

21 January, 2016

 

Biochar Trial Update, Charging Biochar & a Rock Dust Field Trial?

On February 15th, I’ll be starting an indoor biochar trial, in which I’ll compare plants grown in a potting mix that includes biochar versus the same plants grown in a similar potting mix with no biochar.

Other members of the Home Garden Field Trials community, including TheSelfSufficientLife, SouthpawDavey, and Nick Peters will also be conducting trials, and I’d like to take this opportunity to thank everyone who will be participating or following the trials.

In this video, I’ll talk about my interest in evidence based gardening, what hypotheses I hope to test in the indoor trial, a little bit about the design of the trial, and why participating in the trial doesn’t have to be as big of a hassle as I sometimes make it seem.

I’ll also give an update on my latest preparation for the trial, which was to charge and inoculate my biochar with worm castings.

Home Garden Field Trials:

One Yard Revolution is all about growing a lot of food on a little land using sustainable organic methods, while keeping costs and labor at a minimum. Emphasis is placed on improving soil quality with compost, mulch, and compost tea. No store-bought fertilizers, soil amendments, pesticides, compost activators, etc. are used.

biochar application guidelines

I am presently in Belize and recently visited a research farm that advocates the use of Bio Char based on their study of ancient Mayan techniques and their uses of it to promote rooting and higher yields.

Can you direct me to data sources that can be used to engineer
the application of Biochar to a 1000 sq.garden that, based on CSU soil test lab results, is otherwise suitable for home garden use?

The garden of concern is in Aurora, Co and has been enriched to provide a sandy loam by addition of composed manure, wood chips, both in soil and as a mulch, to improve water retention over a 15 year period.

Cleaning Water Contaminated with Heavy Metal Ions Using Pyrolyzed Biochar Adsorbents

27 January, 2016

The extraction of pollutants from water using activated biochar materials is a low cost, sustainable approach for providing safe water in developing countries. The adsorption of copper ions, Cu (II), onto banana peels that were dried, pyrolyzed and activated was studied and compared with the adsorption of copper ions onto a commercial activated carbon, F-400. Both the physical and chemical properties of the banana peel and activated carbon were measured. Pyrolysis of dried banana peels resulted in the formation of a large, porous surface area adsorbent with strongly negative surface charges. Screening studies, which were designed to evaluate the effect of the mass of the adsorbent, pH of the solution, tumbling time, and initial Cu (II) concentration were conducted for each adsorbent. Equilibrium adsorption data were also analyzed, and the Freundlich isotherm resulted in a better fit than the Langmuir isotherm. The degree of favorability of adsorption of Cu (II) ions and adsorption capacity were 1.25 and 351.1 mg/g for pyrolyzed banana peel, respectively. The sorption kinetics fit a pseudo-second order equation.

Biochar are created by pyrolysis to biomass and it’s also a kind of charcoal. It’s believed that this product was first developed simply by on Pre-Columbian Amazonians. It has been found that Pre-Columbian Amazonians released our product simply by smoldering agricultural spend at big trenches. Biochar is furthermore utilized by Europeans at early times, that labeled this terra preta de Indio. It’s fundamentally employed for boosting soil excellence for agricultural cause. Because time passed, our soil excellence booster became well-accepted in the agriculture globe pre-columbian pottery for sale and it’s also undoubtedly the greatest alternative to compound fertilizers. Researchers have discovered down that Biochar might safeguard plants off some soil-borne conditions. There are numerous considerably issue which have established our natural soil excellence booster popular in the agricultural globe.Biochar of Carbon SequestrationScientists believe biochar might immensely help in mitigating climatic adjustment thru carbon sequestration. This method are achieved for making the best long-term storage space for atmospheric carbon dioxide inside mitigate global warming to climatic adjustment being in charge of this. Biochar are the best bright ray to expect countless researchers, who’re undertaking researches to guard the environmental surroundings from adjustment caused by global warming. Worldwide warming is like your alarm for the individual globe to stop ways that are not at sync with all the ecosystem, to biochar is among the well solutions with this problem.

Anyhow, the commonly held view usually people of the Clovis tradition are the first, then are identified with web sites returning to nearly14,000 many years. Later on, web sites because aged because 20,000 many years have already been found, then genetic researches trigger the conclusion that the very first batch of migrants reached the shores of Americas some time between 40,000 to 13,000 years back. Still another belief is that the lands are populated with several waves of immigrants.The Austronesians concerning contemporary latest Guinea as well as the indigenous Australians Aborigines maintained get a hold of immediately after geographical separation, when is supported simply by linguistic and genetic evidence.

Such very early inhabitants associated with Americas underway agricultural techniques, raising maize with ears to lengths different starting 2 – 5 cms to 10 -15 cms. Another flowers grown up through consumers are potatoes, pumpkins, tomatoes and/or avocadoes. As very few best suited species are available, there have been very few livestocks. For meat, but some sort of guinea pig was raised within the Andes. Maize was taken from Mexico within the fifteenth century CE towards the Mississippi embayment and/or was grown up as one agricultural crop truth be told there, nevertheless further developments weren’t potential because of the arrival associated with Europeans during those times. The Incas expanded potatoes, as the Aztecs farmed cocoa found in chocolates. If the Europeans found its way to united states, lots of Natives there have been semi-nomadic tribes to hunter gatherers. Others owned by agricultural and/or inactive societies created newer tribes to confederations at retaliation towards European colonization. One of them, some sort of well-known teams are some sort of Apache, some sort of Cherokee, some sort of Sioux, some sort of Iroqouis and also the Mohegan. The Iroquois contains numerous sub-groups including Mohawk, Oneida, Seneca, Cayuga, Onandaga and/or afterwards, some sort of Tuscarora tribe. The Inuits are definitely the best later choice towards like teams. There have been numerous pre-Columbian inactive societies in our time United States of America, not so politically complicated and/or technologically high level due to the fact Mesoamerican civilizations straight down southern are.

After will evolution out of people on earth, one geological duration measure defines periods at prehistory. Archaeology supplemented this particular record delivering considerably exact divisions. Commonly, prehistory into the aged worldwide are designated through one three age system. This method categorizes individual prehistory underneath 3 straight time periods, named because of their respective prevailing tool-making technology. In New World, but more naming schemes are employed, as an example, people placed in Archaeology associated with Americas. But, that loosely defined systems out of dividing increase prehistory aren’t quite accurate due to the fact present archaeological discoveries recommend a more specialized thought out of prehistory.Before some sort of Europeans arrived, for countless ages many living over the northern coastline, that is, some sort of Kimberley region out of Western Australian Continent, Arnhem Property, Gulf out of Carpentaria and Cape York had interacted and exchanged with people from outdoors. Even with some sort of secure bridgework were submerged that even ahead of the occasion, commodities out of trade and many moved easily anywhere between brand new Guinea and Australian Continent 6,000 years ago. Using the bridgework flooded, some sort of trade and individuals towards many get a hold of proceeded across the newly-formed Torres Strait, whoever one hundred fifty kilometre width ended up being navigated by stopping at intermediate isles and coral reefs along the way. Settlers as part of those isles were seagoing Melanesians, additionally the native Australians off northeast of continent maintained a cultural link to the surface globe through your route not exactly 2,500 years ago. All visits of Indonesians additionally the individuals of brand new Guineea toward Australians and vice versa for fishing and trade by sailing crafts indicate the chance out of like forays by some sort of Arab additionally the China investors that earlly that 9th century CE. All controversial Bradshaw figurines as part of Kimberley art tend to be stated to possess been brought by Indian visitors inside very early many years of some sort of Religious age. For several hundred years, Indonesian Bajini fishermen off Spice isles e.g., Banda Island had fished from the shore out of Australian Continent. Not Quite, 400 years ago Macassan investors out of Sulawesi Celebes regularly came to some sort of northern shore out of Australian Continent for trepang a edible water cucmber towards trade with the China.
