SYNOPSIS

Darby and I visited one of our ISA on-farm trial sulfur plots in Vermilion County this week. Soybeans are ready to be harvested, but we are hoping for rain Saturday as conditions are extremely dry. We tried digging soybean plants in different treatments of the trial and, unfortunately, bent the shovel. There are many reports of soybeans still holding leaves and green stems but with very low grain moistures. Corn has been harvested in the area, and yields are above average but less than the record yields reported last year. Corn tip-back was seen on some ears, and disease was visible in the upper corn canopy.
