Nitrous oxide fluxes, soil oxygen, and denitrification potential of urine- and non-urine-treated soil under different irrigation frequencies
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2016-07)
© American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America. 5585 Guilford Rd., Madison, WI 53711 USA. All rights reserved. Despite increased use of irrigation to improve forage ...
Lime and soil moisture effects on nitrous oxide emissions from a urine patch
(Soil Science Society of America, 2004)
Liming has been mooted as a mitigation option for lowering soil N₂O emissions. This study investigated the effect of soil pH and soil water content on N₂O and N₂ emissions following the addition of synthetic urine (500 kg ...
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 ...
Nitrite accumulation and nitrogen gas production increase with decreasing temperature in urea-amended soils: Experiments and modeling
(Elsevier, 2020-03)
Nitrite (NO₂⁻) accumulation and associated production of nitric oxide (NO) and nitrous oxide (N₂O) gases in soils amended with nitrogen (N) fertilizers are well documented, but there remains a poor understanding of their ...
Role of plants in reducing nitrogen losses
(Royal Society of New Zealand, 2020-01-19)
We are pleased to present this special issue, ‘Role of plants in reducing nitrogen losses’. This issue brings together a group of studies that have focused on the role of crops and forages in mitigating nitrogen (N) losses ...
Dairy farm effluent effects on urine patch nitrous oxide and carbon dioxide emissions
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2005)
Dairy farm effluent (DFE) comprises animal feces, urine, and wash-down water collected at the milking shed. This is collected daily during the milking season and sprayed onto grazed dairy pastures. Urine patches in grazed ...
Ruminant urine patch nitrification and N₂O flux: Effects of urine aucubin rate in a laboratory trial
(Taylor & Francis on behalf of Royal Society of New Zealand, 2019-06-10)
Livestock urine deposition onto grazed New Zealand pastures drives soil nitrous oxide (N₂O) emissions. Urine patch N₂O emissions can be reduced by inhibiting nitrification, a key urine patch nitrogen (N) transformation ...
Nitrous oxide fluxes and soil oxygen dynamics of soil treated with cow urine
(Soil Science Society of America, 2017-04-20)
Ruminant urine deposition onto pasture creates hot-spots where emissions of nitrous oxide (N₂O) are produced by aerobic and anaerobic microbial pathways. However, limited measurements of in situ soil oxygen (O₂)-N₂O ...
Irrigation of DOC-rich liquid promotes potential denitrification rate and decreases N₂O/(N₂O+N₂) product ratio in a 0–2 m soil profile
(Elsevier, 2017-03)
Lack of dissolved organic carbon (DOC) is generally one of the key factors limiting denitrification in subsoil beneath the root zone. Despite a number of laboratory DOC amendment studies, the effects of in situ DOC ...
Fertiliser and seasonal urine effects on N₂O emissions from the urine-fertiliser interface of a grazed pasture
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2015)
Significant areas of ruminant-grazed pastures are simultaneously covered by excreted urine and fertiliser nitrogen (N). However, the effect of overlapping N inputs on nitrous oxide (N₂O) emission factors has not been ...
