Gray County, Southwest, Kansas | Min- 210bu Max-260 bu on every hard ground circle. we have some circles in the sand that have a Min-120 Max-180 but we don’t variable rate anything down there.
I guess I used the wrong term we soil sample off management zones based on soil types. I use the readings and build a variable rate NH3 map when we strip till in the fall
Almost every time we take soil samples they come back not needing anything other than 150 to 200 lbs of N
