I was wanting to know why we should only apply 100 lbs max of nh3 for strip till. We strip till in s.e. Kansas with 150 -180 lbs and as far as we can tell we haven't noticed anything unusual.

Hi Mike, I am basing my statements in part off some Kansas State University (KSU) Agronomy Field Research that was done in 2006. The primary research was conducted by K. A. Janssen. Perhaps my wording was too strong. There's nothing particularly wrong with your approach, it's just that you’re probably putting on more than you need. It's a good idea to use as little N as you can get away with, both for economic reasons and to prevent excess runoff. -But maybe your soil needs that much extra - hard to say without looking at his chemistry. I would suggest testing the theory and “underapply" (by your standards) N on a small section this coming year. Then check the yields to see if you’re getting anything for the extra 50-80 lbs. Keep in mind that farming is an art and no two fields are exactly the same. We can’t write an end-all be-all instructional, even though we try. Thanks for writing in and be sure to let me know how it works out!
