Biochar is a carbon‐rich coproduct resulting from pyrolyzing biomass. When applied to the soil it resists decomposition, effectively sequestering the applied carbon and mitigating anthropogenic CO2 emissions. Other promoted benefits of biochar application to soil include increased plant productivity and reduced nutrient leaching. However, the effects of biochar are variable and it remains unclear if recent enthusiasm can be justified. We evaluate ecosystem responses to biochar application with… 

Effects of biochar on soil processes, soil functions and crop growth

Biochar is the carbon-rich product obtained when organic material is pyrolyzed, during which bioenergy is produced. When applied to soil, biochar is claimed to have positive effects on soil

The impact of biochar on nitrous oxide emissions and nitrogen cycling in temperate cropland soils

Biochar, a carbon-rich, porous pyrolysis product of organic residues may positively affect plant yield and can, owing to its inherent stability, promote soil carbon sequestration when amended to

Functional response of the soil microbial community to biochar applications

Biochar has the potential to mitigate the impacts of climate change and soil degradation by simultaneously sequestering C in soil and improving soil quality. However, the mechanism of biochar's

The Impact of Woody Biochar on Microbial Processes in Conventionally and Organically Managed Arable soils

ABSTRACT Although environmental impacts of biochar are well characterized, impacts on soil quality, nutrient availability and crop productivity, still remain a challenge due to the diverse response

Variable effects of biochar and P solubilizing microbes on crop productivity in different soil conditions

ABSTRACT An expanding body of literature informs that biochar improves soil quality and agricultural productivity. However, there are some reports of little, or even negative, effect of biochar on

Effects of Biochar Application on Beneficial Soil Organism Review

Biochar is the carbon-rich product obtained when biomass is heated in a closed container with little or no available air with the purpose to amend soil and means to sequester carbon (C) and maintain

Biochar and their impacts on soil properties and crop productivity: a review

Biochar may be added to soils with the goal to improve the soil properties and relocate an amount of conventional fossil fuel based fertilizers, and sequester carbon. Biochar stability is critical to

Effect of biochar and liming on soil nitrous oxide emissions from a temperate maize cropping system

Abstract. Biochar, a carbon-rich, porous pyrolysis product of organic residues may positively affect plant yield and can, owing to its inherent stability, promote soil carbon sequestration when



Effects of biochar compared to organic and inorganic fertilizers on soil quality and plant growth in a greenhouse experiment

Our contemporary society is struggling with soil degradation due to overuse and climate change. Pre-Columbian people left behind sustainably fertile soils rich in organic matter and nutrients well

Biochar and manure affect calcareous soil and corn silage nutrient concentrations and uptake.

If the second year results are representative, they suggest that biochar applications to calcareous soils may lead to reduced N availability, requiring additional soil N inputs to maintain yield targets.

Ethylene: potential key for biochar amendment impacts

Significant increases in root density, crop growth and productivity have been observed following soil additions of biochar, which is a solid product from the pyrolysis of biomass. In addition,

Influence of biochar on drought tolerance of Chenopodium quinoa Willd and on soil–plant relations

The application of pyrogenic carbon, biochar, to agricultural soils is currently discussed as a win-win strategy to sequester carbon in soil, thus improving soil fertility and mitigate global

Influence of biochar on nitrogen fractions in a coastal plain soil.

The observed responses to different biochars illustrate the need to characterize biochar quality and match it to soil type and land use and the effect of biochar on soil N dynamics was evaluated.

Decreased soil microbial biomass and nitrogen mineralisation with Eucalyptus biochar addition to a coarse textured soil

Background and AimsBiochar has been shown to aid soil fertility and crop production in some circumstances. We investigated effects of the addition of Jarrah (Eucalyptus marginata) biochar to a coarse

Impact of Biochar on Manure Carbon Stabilization and Greenhouse Gas Emissions

Previous studies indicate that biochar additions sometimes increase soil respiration and CO 2 emissions which could partially offset C credits associated with soil biochar applications. Little is
