SW Ohio | I recently pulled some soil samples of land I started farming in 2018. This was in grass hay for quite a few years until I planted Soybeans in 2018, I saw what I suspected was signs of K deficiency in the soybeans. Got the soil test results today and it is indeed low in K. What I am having trouble with is how much fertilizer to apply. I am planting corn there this year, shooting for 180-200bu/ac. I know that the corn will remove 70 lb phosphate and 50lb potassium, I can't remember how to use my soil test numbers to calculate a fertilizer recommendation. TIA
