End of season stalk nitrate testing is here in most areas. Best time to take sample is 1-3 weeks after black layers have formed on about 80 percent of the kernels of most ears. The portion of each plant sampled is the 8-inch segment of stalk found between 6 and 14 inches above the soil. We need 15 of these segments. Fall soil sampling is just around the corner. Order your supplies on line or call the lab to place your order.
