Ontario Corn, Soy Crops Still Facing Production Risks

Ontario corn and soybean crops have shown major improvement with better rainfall and cooler temperatures over the past several weeks, but production risks remain. 

Big corn plants and lush soybean fields give the appearance of strong yield potential that may not actually translate at harvest, Real Agriculture agronomist Peter Johnson said Wednesday. 

“Rain in August makes soybeans, and we are getting rain, so the crop should be excellent,” he said. “But many growers would think, ‘record crop,’ and for some reason it doesn’t always turn out that way with extremely lush soybeans.”

Corn pollination may be behind us, but the work isn't over.

In this field update from the Nutrien Innovation Farm in Champaign, Illinois, agronomist Tim Sickman discusses why growers should stay engaged with field scouting during the R3 (milk) stage of corn development. While favorable weather, strong pollination, and early grain fill are encouraging signs, important questions about crop nutrition and yield potential still remain.
