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… Expand
Combined effects of biochar properties and soil conditions on plant growth: A meta-analysis.
A meta-analysis will provide helpful information to elucidate the combined effect of biochar properties and soil conditions on plant growth, which is critical for developing engineered biochar with specific functionality to promote plant production and food security. Expand
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 toExpand
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 soilExpand
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'sExpand
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 responseExpand
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 onExpand
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 maintainExpand
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 toExpand
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 whenExpand
Influence of biochar aged in acidic soil on ecosystem engineers and two tropical agricultural plants.
The data revealed that biochar did not increase the belowground biomass of the plant species during the 90 d biochar-soil contact time, indicating a direct toxic influence of biochar on plant roots, and reveals that nutrient availability is not the only mechanism involved in biota-biochar interactions.

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 wellExpand
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. Expand
Contrasted effect of biochar and earthworms on rice growth and resource allocation in different soils
Abstract Adding biochar to soils and maintaining high earthworm biomasses are potential ways to increase the fertility of tropical soils and the sustainability of crop production in the spirit ofExpand
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,Expand
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 globalExpand
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. Expand
Biochar effects on soil biota – A review
Soil amendment with biochar is evaluated globally as a means to improve soil fertility and to mitigate climate change. However, the effects of biochar on soil biota have received much less attentionExpand
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 coarseExpand
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 isExpand
