2019 Seminar Series - Dr. John Sulik


Management zone considerations for southern Ontario

by Dr. John Sulik, Department of Plant Agriculture, University of Guelph

LOCATION: Room 202, Crop Sci
DATE & TIME: Thursday, January 31, 2019 @ 11:00 AM


This presentation will explore relationships between geospatial data layers that may be relevant for delineating management zones in southern Ontario. The discussion will start by explaining the fundamentals of vegetation indices and how they can be used to map spatial variation in water stress using freely available satellite imagery. Next, we will explore how corn grain yield is related to variation in soil electroconductivity, surface temperature, and remote sensing indices. Most of this presentation will be exploratory data analysis and explain John’s perspective on how we can advance digital agriculture in Ontario.



John has a PhD in geography from Florida State University. His first taste of agricultural research was working on canola with the Agricultural Research Service of the USDA in Oregon. He went on to work for a precision ag company and then a company that sells multispectral sensing systems. He is interested in field crops and horticultural crops and improving their management through use of precision ag technologies.
