Donnellson, IA. Makes saying here easier. | All the preplant guys with the greatest success are you all nh3 guys? Also curious how many sidedress with nh3? We use multiple forms and have tried many timings and amounts. Just curious to see if the post nh3 sidedress guys had more success than 32% or urea. My highest efficiency and yield were the same season. Fall N at 70N nh3....6N in 10-34-0 at planting....75N 32% ats ydrop.
For years we we're all nh3 post. But drier seasons we have trouble sealing and keeping it from leaving.

Whats the point of preplant even half of Nitrogen in corn?
