NH3 Toxicity

Seeing patterns in the wheat again this year as it relates to last fall's NH3 bands. Applied on 12" spacing at probably 4" deep last October and wheat seeded early May. Pea stubble and of course we are dry here but some moisture. I think these patterns are more visible in cereals because the seed row is continuous and any missing/stunted plants are very noticeable.

The missing seeds look like this.

My broadcast urea fields look great and my best crop ever was grown(two years ago) with broadcast urea and shallow incorporation with tillage. I'm starting to wonder if rates are getting a bit too high to concentrate them in a band. Even last year I had some corn planted same direction as urea banded a few days prior and it didn't like that at all.

I am surprised that NH3 can hang on like this even after a winter and affect a crop in such an adverse way. Having said this the field that showed these symptoms worst last year yielded the best, but mostly because it caught an extra inch of rain...ha ha
