Global Research Alliance N₂O chamber methodology guidelines: Introduction, with health and safety considerations
(Wiley on behalf of American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2020-09)
Non-steady-state (NSS) chamber techniques have been used for decades to measure nitrous oxide (N₂O) fluxes from agricultural soils. These techniques are widely used because they are relatively inexpensive, easy to adopt, ...
Potential inhibition of urine patch nitrous oxide emissions by Plantago lanceolata and its metabolite aucubin
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2017-12-12)
Plantain (Plantago lanceolata L.), a forage used in grazed pastures, contains active secondary metabolites that could potentially inhibit nitrification, a key step in nitrous oxide (N₂O) production from grazing ruminant ...
Assessing the impact of non-urea ruminant urine nitrogen compounds on urine patch nitrous oxide emissions
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2018-07)
Urea, the dominant form of N in ruminant urine, degrades in soil to produce N2O emissions. However, the fate of non-urea urine N compounds (NUNCs) in soil and their contribution to urine patch N2O emissions remain unclear. ...
Urea treatment decouples intrinsic pH control over N₂O emissions in soils
Soil N₂O emission potential is commonly investigated under idealized denitrifying conditions (e.g. nitrate-N supplied and anaerobic soil), with pH commonly identified as a major determinant of N₂O emission potential. ...
Potential for forage diet manipulation in New Zealand pasture ecosystems to mitigate ruminant urine derived N₂O emissions: a review
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2016)
Nitrous oxide (N₂O) emissions from agricultural soils account for more than 10% of New Zealand’s greenhouse gas emissions. Livestock urine deposition drives N₂O losses from these soils. It has been speculated that non-urea ...
