Biochar incorporation into pasture soil suppresses in situ nitrous oxide emissions from ruminant urine patches
(Crop Science Society of America, Soil Science Society of America, and American Society of Agronomy, 2011-03)
Nitrous oxide (N₂O) emissions from grazing animal excreta are estimated to be responsible for 1.5 Tg of the total 6.7 Tg of anthropogenic N₂O emissions. This study was conducted to determine the in situ effect of incorporating ...
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 ...
Seasonally distinct sources of N₂O in acid organic soil drained for agriculture as revealed by N₂O isotopomer analysis
(Springer Nature, 2020-01-01)
Acid organic soils drained for agriculture are hotspots for nitrous oxide (N₂O) emissions. Previous studies have indicated that water table (WT) depth and nitrogen (N) availability are important environmental controls, ...
Nitrous oxide dynamics in agricultural peat soil in response to availability of nitrate, nitrite, and iron sulfides
(Taylor & Francis, 2019-09-24)
Drained agricultural peat soils are potential hot spots of nitrous oxide (N₂O) emissions, but the biogeochemical basis for distinctively large emissions is still unclear. Incubation experiments with acidic bog peat, using ...
