Current research programme
The current focus of the NZAGRC’s nitrous oxide (N2O) research programme is on measuring the effects pasture plants and pasture plant communities have on nitrous oxide emissions.
This work is closely aligned to the MBIE P21 and Forages for Nitrate Leaching programmes (FRNL). In addition, an investigative project on a technology to locate and treat urine patches was completed in 2015/16.

Irrigation effects modelled
The CenW model developed for Waikato farms was compared against three years of eddy-covariance data from an irrigated grazed pasture in the Canterbury region. CenW was used to compare three irrigation management scenarios: no irrigation (dairy grazed), real life irrigation (dairy grazed), and sheep grazing (no irrigation or fertiliser). This initial modelling demonstrated that carbon accumulation was maximised with about 1100mm of combined rainfall and irrigation.
