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.”

Field Talk Friday | Dr. John Murphy | Root Exudates, Soil Biology, and How Plants Recruit Microbes

Most of us spend our time managing what we can see above ground—plant height, leaf color, stand counts, and yield potential. But the deeper you dig into agronomy, the more you realize that some of the most important processes driving crop performance are happening just millimeters below the surface.

In this episode of Field Talk Friday, Dr. John Murphy continues the soil biology series by diving into one of the most fascinating topics in modern agronomy: root exudates and the role they play in shaping the microbial world around plant roots.

Roots are not passive structures simply pulling nutrients out of the soil. They are active participants in the underground ecosystem. Plants constantly release compounds into the soil—sugars, amino acids, organic acids, and other molecules—that act as both energy sources and signals for soil microbes.
