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 ...
Effectiveness of the nitrification inhibitor dicyandiamide and biochar to reduce nitrous oxide emissions
(Taylor & Francis on behalf of The Royal Society of New Zealand, 2016)
Animal urine from grazing animals is responsible for the majority of New Zealand’s nitrous oxide (N₂O) emissions. A field lysimeter study was conducted to determine the ability of the combination of the nitrification ...
Comparison of nitrate leaching from oats and Italian ryegrass catch crops following simulated winter forage grazing: a field lysimeter study
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2017)
Intensive winter forage grazing systems have a high risk of environmental impact due to nitrate (NO₃⁻) leaching from urine deposition on cool, wet, fallow soils. We investigated the effect of sowing two catch crops after ...
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 ...
