Professor Surinder Saggar

Professor

School of Agriculture and Environment

Professor Surinder Saggar is nationally and internationally recognised for his leading research to understand the microbial processes regulating losses of agricultural nitrogen to the atmosphere and to groundwater to improve nitrogen use efficiency by identifying effective strategies for reducing its losses, to benefit farmers and the environment. Also notable here is his earlier research on other nutrients phosphorus and sulphur, as well as enhancing soil carbon storage.

Internationally, he championed a tripartite Memorandum of Understanding among Massey University, Landcare Research and Punjab Agricultural University to strengthen the research collaboration and post-graduate student and staff exchange, held a Visiting Professorship at the National Council of Chile, was Senior Research Fellow of the Japanese Society for the Promotion of Science, has delivered plenary and keynote addresses at international conferences, and this year has been invited by the IAEA in Vienna to assist them to develop a Coordinated Research Project to minimize farming impacts on climate change.

Among Surinder’s awards acknowledging the excellence of his research have been the Norman Taylor, and the M L Leamy Awards, from the New Zealand Society of Soil Science.  He is a Fellow of this Society and also of the New Zealand Institute of Agricultural and Horticultural Science. He has also been nominated Fellow of the Royal Society of New Zealand. Internationally, he established the Global DNDC Network, aimed at assisting countries to estimate and verify their nitrous oxide emissions, is a member of the America-New Zealand Soil Science Professional Exchange Fund Committee of the SSSA and also maintains an active role as editor for high profile journals including Agriculture, Ecosystems and Environment, Science of the Total Environment and Soil Biology and Biochemistry. .

Professor Surinder Saggar has an outstanding record of research and service in agriculture, both in India, where he spent first few years of my career, and in New Zealand, where he is  currently based at Landcare Research, Palmerston North. A soil scientist with more than 40-year experience in soil biogeochemistry, he has been instrumental in managing and planning of research across a broad spectrum in agriculture science, and conducting research and consultancy on nutrient management in sustainable primary production systems and in greenhouse gas emissions. He has also contributed to the extension and adoption of this research.
