Nitrous Oxide Emissions from Dairy Farmlets, as Affected by Use of a Nitrification Inhibitor and a Winter Restricted Grazing Strategy
Experimental farmlets at DairyNZ’s Prototype Farm near Hamilton were used to determine potential reductions in nitrous oxide (N2O) emissions from use of a nitrification inhibitor and a restricted grazing regime. A control farmlet was managed under a conventional rotational grazing regime, while a “tight nitrogen” farmlet was managed under a similar grazing regime to that on the control farmlet,...
متن کاملNitrous Oxide Nitrification and Denitrification
The isotopic signatures of N and O in N2O emitted from tropical soils vary both spatially and temporally, leading to large uncertainty in the overall tropical source signature and thereby limiting the utility of isotopes in constraining the global N2O budget. Determining the reasons for spatial and temporal variations in isotope signatures requires that we know the isotope enrichment factors fo...
متن کاملMitigation of nitrous oxide emissions with nitrification inhibitors in temperate vegetable cropping in southern Australia
Intensive vegetable production in southern Australia is characterised by high inputs of nitrogen (N) fertiliser, water, and occasionally animal manures, which creates the potential for high nitrous oxide (N2O) emissions. Three field experiments were conducted to investigate the effects of the nitrification inhibitors 3, 4-dimethylpyrazole phosphate (DMPP), 3-methyl pyrazole plus 1H-1,2,4 triazo...
متن کاملNitrification inhibitors can increase post-harvest nitrous oxide emissions in an intensive vegetable production system
To investigate the effect of nitrification inhibitors (NIs) 3,4-dimethylpyrazole phosphate (DMPP) and 3-methylpyrazole 1,2,4-triazole (3MP + TZ), on N2O emissions and yield from a typical vegetable rotation in sub-tropical Australia we monitored soil N2O fluxes continuously over an entire year using an automated greenhouse gas measurement system. The temporal variation of N2O fluxes showed only...
متن کاملKinetic and Thermodynamic Behaviors of Soil Urease as Affected by Urease Inhibitors
The kinetic characteristics of soil urease have attracted great attention, but little information was available on its kinetic and thermodynamic behaviors as affected by urease inhibitors and temperature. With black soil (Pachic Udic Mollisol) in Heilongjiang Province of Northeast China as a test soil, an incubation test was conducted to investigate the effect of urease inhibitors (hydroquinone...
