Comprehensive research undertaken in NZ has already demonstrated that nitrification inhibitors (NI) can provide an effective method for reducing N<sub>2</sub>O emissions from urine patches deposited on pasture. Research funded by NZAGRC will address the challenge of optimising inhibitor use so that their effectiveness and longevity is increased.

Denitrification is the primary process of N<sub>2</sub>O production in New Zealand pasture soils. However, we lack a comprehensive, quantitative understanding of denitrification rates and controlling factors across agrosystems. This Objective will test and improve the latest microbiological and tracer techniques to identify pathways for reducing N<sub>2</sub>O production during denitrification and develop mitigation technologies that reduce N<sub>2</sub>O emissions by lowering N<sub>2</sub>O/N<sub>2</sub> ratio during denitrification.

The aim of this research is to develop better fundamental understanding of the role that soil physical characteristics and changing soil water conditions affect N<sub>2</sub>O emissions, and use this knowledge to produce a scientifically robust and easily measurable relationship between soil water or aeration status and N<sub>2</sub>O. In turn, we will use this knowledge to help refine on-farm grazing and soil water management decision-making to minimise N<sub>2</sub>O emissions.
