Nitrous Oxide

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.

NOT LONGER AVAILABLE PhD in Greenhouse Gas Emissions from Grazed Pastures
University of Waikato, New Zealand

We have an opening for a PhD candidate to make measurements of nitrous oxide and carbon dioxide fluxes from grazed pastures using eddy covariance and chamber techniques. Our team is currently measuring fluxes of carbon dioxide at four eddy covariance tower sites over grazed pastures. We have recently installed a quantum cascade laser system to measure nitrous oxide fluxes. The successful candidate will initially test whether chamber measurements of nitrous oxide match those of the eddy covariance tower. Our ultimate aim is to identify farm management strategies that decrease nitrous oxide emissions while increasing soil carbon and maintaining pasture production.

Ideally, you will have experience or strong understanding of measurement of greenhouse gases, such as nitrous oxide, and the ability and motivation to learn eddy covariance techniques. A background in Matlab or similar scripting computer language is desired.

This PhD is co-funded for three years by the University of Waikato and the NZ Agricultural Greenhouse Gas Research Centre (NZAGRC). Expressions of Interest must be submitted via the online form by 1 December 2016 at If no applicant is appointed the scholarship will remain open until a suitable applicant is found.

You will be part of a motivated team of researchers and students at the University of Waikato with considerable experience in flux measurements. The PhD candidate will be supervised by Drs Louis Schipper, Dave Campbell and Liyin Liang. Our research team can be viewed:
