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 ...
¹⁵N recoveries from ruminant urine patches on three forage types
(Springer Verlag on behalf of the Royal Netherlands Society of Agricultural Science, 2017-05-17)
Background and aims: ¹⁵Nitrogen balances are useful tools to increase our understanding of soil N processes and the efficiency of plants in taking up animal urine-N. This study aimed to investigate the effect of forage ...
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 ...
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 ...
Nitrate leaching losses are lower from ryegrass/white clover forages containing plantain than from ryegrass/white clover forages under different irrigation
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2018-04-18)
The aim of this research was to assess the potential of using perennial ryegrass (Lolium perenne) and white clover (Trifolium repens) forages containing plantain (Plantago lanceolata L.) (PRGWC + Plantain) to mitigate ...
Effect of two irrigation rates on nitrate leaching from diverse or standard forages receiving spring deposited urine
(Royal Society of New Zealand and Taylor & Francis, 2017-12-20)
The effect of two irrigation rates on nitrogen (N) harvested by diverse and standard forages, and the subsequent effect on nitrate (NO₃⁻) leaching losses from spring deposited urine was investigated. An experiment, using ...
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. ...
Accounting for the utilization of a N₂O mitigation tool in the IPCC inventory methodology for agricultural soils
(Springer Netherlands, 2007)
In this study we review recent studies
where dicyandiamide was used as a nitrification inhibitor to reduce both N₂O emissions from urine patches and nitrate leaching from pasture systems, and which led to the development ...
Reducing nitrogen leaching losses in grazed dairy systems using an Italian ryegrass-plantain-white clover forage mix
(Wiley on behalf of the British Grassland Society and the European Grassland Federation, 2018-12)
In grazed agricultural systems, animal urine patches are the major source of nitrogen (N) leaching losses and can cause a decline in water quality. Urine-N rates often exceed plant requirements, and there is a need for ...
Effects of dairy shed effluent dry matter content on ammonia and nitrous oxide emissions from a pasture soil
(Cambridge University Press, 2018-11-01)
Atmospheric emissions of nitrogen (N) from New Zealand dairy farms are significant but have the potential to be affected by manure management prior to land application. The current work examined whether reducing cattle ...
