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
(Frontiers, 2018-11-13)
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 ...
