End of season stalk nitrate time will soon be here to help evaluate N uptake in corn plants. Sampling is between 1 and 3 weeks after black layers have formed on about 80 percent of the kernels of most ears. 15 - 8-inch segments, 6 inches above soil take the next 8 inches of stalk. See our End of Season Stalk Nitrate Test guide in our internet library for complete information.

Fall soil sampling is around the corner and now is the time to start stocking up on sample bags, shipping boxes and probes. Supplies can be ordered on line via the website or calling the office.
