Unweathered wood biochar impact on nitrous oxide emissions from a bovine-urine-amended pasture soil
(Soil Science Society of America, 2010)
Low-temperature pyrolysis of biomass produces a product known as biochar. The incorporation of this material into the soil has been advocated as a C sequestration method. Biochar also has the potential to influence the ...
A wood based low-temperature biochar captures NH₃⁻N generated from ruminant urine-N, retaining its bioavailability
(Springer Netherlands on behalf of the Royal Netherlands Society of Agricultural Science, 2012-04)
Aims: Ammonia (NH₃) can be volatilised from the soil surface following the surface application of nitrogenous fertilisers or ruminant urine deposition. The volatilisation of NH₃ is of agronomic and environmental concern, ...
Biochar adsorbed ammonia is bioavailable
(Springer Netherlands, under the auspices of the Royal Netherlands Society of Agricultural Science, 2012-01)
Biochar is produced as a by-product of the low temperature pyrolysis of biomass during bioenergy extraction and its incorporation into soil is of global interest as a potential carbon sequestration tool. Biochar influences ...
Identification and verification of key functional groups of biochar influencing soil N₂O emission
(Springer Nature, 2021-01-26)
Biochars containing abundant and diverse functional groups can influence soil nitrous oxide (N₂O) emissions. It remains unclear how these functional groups alter soil N₂O emissions and which specific functional groups are ...
Biochar's role as an electron shuttle for mediating soil N₂O emissions
(Elsevier, 2019-06-01)
The functionality of biochar as an electron shuttle has been hypothesized to rationalize its suppressing effect on nitrous oxide (N₂O) emissions from soil denitrification. However, this hypothesis has not yet been ...
Effect of pine waste and pine biochar on nitrogen mobility in biosolids
(Crop Science Society of America, American Society of Agronomy, and Soil Science Society of America (ACSESS), 2016-01)
Humanity produces ~27 kg of dry matter in biosolids per person per year. Land application of biosolids can improve crop production and remediate soils but may result in excessive nitrate N (NO₃⁻N) leaching. Carbonaceous ...
Biochar does not affect soil N-transformations or microbial community structure under ruminant urine patches but does alter relative proportions of nitrogen cycling bacteria
(Elsevier, 2014-06-15)
Nitrogen (N) cycling, especially denitrification, can be significantly altered when biochar is used as a soil conditioner. These alterations in N-cycling have been attributed to a combination of physicochemical change, ...
