Panellist Biographies

Trish Fraser

Trish grew up on a mixed-cropping farm in the north of Scotland. She completed her undergraduate studies at Aberdeen University in 1988 just before coming on a big overseas adventure to conduct postgraduate study at Lincoln University, investigating the fate of urine nitrogen in soil.

Her adventure continued after her studies, with Trish having now worked as a soil scientist for the past 25 years at Plant & Food Research in Lincoln.

Her research has focused on a range of issues related to the management of arable soil systems, for example, the impacts of different cultivation and crop residue management practices on soil properties, as well as understanding the role that earthworms play in influencing soil functions.


Ants Roberts

Ants holds a Bachelor of Agricultural Science (1st Class Honours) and a PhD in Soil Science, both from Massey University. He obtained a Certificate of Completion for the Massey University Sustainable Nutrient Management in New Zealand Agriculture course in 2004 and one for Advanced Sustainable Nutrient Management in 2006. He is a Fellow of the New Zealand Soil Science Society and a member of the New Zealand Institute of Primary Industry Management and the New Zealand Grassland Association.

Ants works as Chief Scientific Officer for Ravensdown Ltd., a farmer-owned co-operative that manufactures and sells fertiliser, lime, products in the agrochemical and animal health areas, and other supporting services (such as ground and aerial fertiliser application, environmental consultancy and precision agriculture technologies).

Before joining Ravensdown in 2002, he worked as a practicing agricultural scientist for 22 years at the Ministry of Agriculture and Fisheries Agricultural Research Division.

His research and consultancy interests included soil fertility (particularly in dairying), agronomy, heavy metal accumulation in agriculture, environmental performance indicator monitoring and interpretation, and waste utilisation or disposal to grazed pasture.

He has also worked in Tasmania, mainland Australia, Japan and South Africa in the area of soil fertility management on pastoral farms.

Over the past 25 years, Ants has not only conducted many soil fertility experiments, but has also actively consulted with pastoral farmers throughout the country on soil fertility management to maximise economic return and minimise off-farm impacts on the environment. Ants' current role involves managing the agronomic research and development for Ravensdown and training the 70 agri managers who work directly with farmers and other staff in soils, fertilisers and pastoral agriculture.


Mike Hedey

Mike Hedley is Professor and Group Leader of Soil and Earth Sciences and Director of the Fertiliser and Lime Research Centre at Massey University.

He has extensive research experience in biogeochemical cycles in grazed pasture systems, with a particular focus on reducing the impact of pastoral agriculture on the environment.

Mike has led the delivery of professional development courses in Sustainable Nutrient Management offered by Massey University for rural professionals.


Andy MacFarlane

Andy and his family farm irrigated land in Mid Canterbury, focused mainly on dairy, but also including deer and beef production. Their farms are recognised for balancing high production with environmental outcomes.

Their home farm, Pencarrow, was awarded the Ballance Farm Environment Award in 2003. Another property in which his family has a major equity share, Kintore Farm, won the Dairy Farm Award, Energy Excellence Award, and Integrated Management Award in the 2013 Ballance Awards.
Within the farm management consultancy practice Andy works at a strategic level as well as with individual farming families. He is known for his expertise and experience in water, soil, and nutrient management issues both at an on-farm and regional level. He also has particular expertise in understanding financial metrics around on-farm systems.
