I don't think you will be with all 28. I feel I need several different forms of nitrogen applied at the right time for each form of nitrogen. I am trying to bring my soil up to a level of calcium, sulfur and nitrate, my soil is more stable. 100 lbs AMS at harvest has helped me alleviate my problems, as I have noted many times on Crop Talk. Broadcast N at the right time on stable soil has been good to me. On rented ground, I need to find out what you are searching for. My results have been good but I probably spent more than I needed to do to get there. Your question is very appropriate. Ed Winkle
