Codenitrification under ruminant urine patch conditions: microbial contributions, substrates and nitrogen flux kinetics
(Lincoln University, 2018)
A large fraction of anthropogenic nitrous oxide (N2O) emissions can be traced back to grazed grasslands, where N2O is mainly emitted from livestock-urine affected soils (so called ‘urine patches’). Since N2O is a potent ...
Impact of biochar coated with magnesium (hydr)oxide on phosphorus leaching from organic and mineral soils
(Springer Verlag, 2018-11-30)
Purpose: Recent research suggests that Swedish organic arable soils have been under-recognized as a potential source of phosphorus (P) loading to water bodies. The aim of this study was to compare P losses through leaching ...
Phosphorus leaching from an organic and a mineral arable soil in a rainfall simulation study
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2018-05-03)
Phosphorus derived from agricultural systems has been found to cause eutrophication of surface waters. To combat this, the specific location of soil profile P release is necessary for development of effective mitigation ...
Differentiated mechanisms of biochar mitigating straw-induced greenhouse gas emissions in two contrasting paddy soils
Straw returns to the soil is an effective way to improve soil organic carbon and reduce air pollution by straw burning, but this may increase CH₄ and N₂O emissions risks in paddy soils. Biochar has been used as a soil ...
