Prof Ian Yule

Director and Professor of Precision Agriculture

Massey Agritech Partnership Research Centre

Professor Ian Yule started his career as a lecturer in Agricultural Engineering at Durham Agricultural College in the UK before moving to the University of Newcastle upon Tyne where he initiated research on precision agriculture. He came to Massey University as a Senior Lecturer in 1997. In 2000 he became the Director of the New Zealand Centre for Precision Agriculture and was made Professor in Precision Agriculture in 2011. Ian holds a PhD in Agricultural Engineering and has a passion for remote and hyperspectral sensing, as well as finding practical, usable solutions to problems within the agriculture space.  

Ian’s work is concentrated on contract research projects, research outputs and postgraduate supervision. Ian is the main supervisor to 6 full time PhD students and carries a $10M portfolio of contracted research activity. Ian has spent the last 10 years concentrating his research efforts on developing remote sensing and imaging.  His work is at the forefront of developing practical applications for remote sensing and imaging that has worked towards NZ’s largest jointly funded (by Ravensdown and MPI) remote sensing project – Pioneering to Precision, PGP Project.

He has extensive knowledge on theory of spectroscopy and the ways of its implementations to improve management of agricultural crops, hill county farms and dairy farms. He has published extensively and actively promotes the work of the centre through presentations to conferences, workshops and professional bodies.
