Many fields in Indiana need potash, especially in high-yield situations, Camberato acknowledges. The best way to find out is through a routine soil-testing program. Lately, however, Casteel and researchers elsewhere have documented that hefty applications of potash shortly before planting corn or soybeans can cause injury that leads to yield reductions.

Fernandez said how phosphorus and potassium are applied does not matter as long as you apply it so test levels are adequate for crop production.
