RealAg Crop Update Ontario: The Threat of Frost Looms as the Countdown to Harvest Continues

This mornings frost warning had some Ontario farmer’s teeth chattering, but it wasn’t the cold that did it. Farmers in the certain counties of Ontario would be understandably nervous depending on how far along their corn crop is. Frost at the wrong time can take a sizeable bite out of your corn yield.
