University of Guelph Names New Ridgetown Campus Director

May 07, 2013

The University of Guelph – Ridgetown Campus has named Ken McEwan as the new director for a five-year term, which began May 1. McEwan will be succeeding Art Schaafsma, who served as director from 2007 to 2011.

Rob Gordon, Dean of the Ontario Agricultural College (OAC) says the Ridgetown community is excited about McEwan’s vision. McEwan has been acting as interim director since Jan. 1, 2012. Prior to that, he was the research co-ordinator at Ridgetown. The director position entails overseeing 120 faculty and staff and an annual budget of $18.5 million.

McEwan has a long history with the college, joining in 1990 as a professor in production economics and agribusiness and teaching at the University of Guelph’s main campus in the Department of Food, Agriculture and Resource Economics. In a press release, McEwan said that it is a privilege to be given this opportunity and says he looks forward to working with community stakeholders in his new role.

Video: Dr. Emerson Nafziger: Nitrogen Fertilizer Rates for Corn

The Crop Science Podcast Show, Dr. Emerson Nafziger from the University of Illinois breaks down decades of nitrogen research. From the evolution of N rate guidelines to how soil health and hybrid genetics influence nitrogen use efficiency, this conversation unpacks the science behind smarter fertilization. Improving how we set nitrogen fertilizer rates for rainfed corn is a key focus. Discover why the MRTN model matters more than ever, and how shifting mindsets and better data can boost yields and environmental outcomes. Tune in now on all major platforms!

"The nitrogen that comes from soil mineralization is the first nitrogen the plant sees, and its role is underestimated."

Meet the guest:

Dr. Emerson Nafziger is Professor Emeritus of Crop Sciences at the University of Illinois at Urbana-Champaign, with degrees in agronomy from Ohio State, Purdue, and Illinois. His research has focused on nitrogen rate strategies and crop productivity. He co-developed the Maximum Return to Nitrogen (MRTN) model, which is widely used across the Midwest. His research spans N response trials, hybrid interactions, crop rotation effects, and yield stability.
