Ammonia and nitrous oxide emissions from soils under ruminant urine patches and the effects of biochar amendment on these emissions and plant nitrogen uptake
(Lincoln University, 2011)
Urine and dung from ruminants contributes to emissions of both nitrous oxide (N₂O) and ammonia (NH3). These are important for a variety of agronomic and environmental reasons. Urine contributes a much larger fraction than ...
