NW Wisconsin | If it were me, I would apply 100# AMS, 100# potash, and split some fields with 100# urea added as well. Nitrogen can be real finicky in my opinion and I’d still want to check to see response levels even if I thought I didn’t need it.
This all assuming broadcast and dry fertilizer only.
Depending on how much you want to mess around, I’d try some acres leaving out the potash but trying some foliar feed throughout the season. K can be difficult under different environmental conditions regardless of soil levels. | |

Do I need fertilizer?
