Minnesota/Kentucky fertility based on ENERGY | So if this would be the case my good friend Keith Schlapkohl would have wrecked his soils 15 years ago, he's applied 2000 lbs. ADM gypsum every year excecpt for the two years which hes only applied 1000 lbs. per acre I've seen his ground increase in P and K. and nitrogen has stayed vary high. Infact he raises CC with under or right at 100 lbs. per acre
I would say watching his farm and many others that you can apply a lot of sulfur if you have ample calcium to go with it since ADM is 38% C and 12% S along several micro nutrients |
