Synopsis Both potassium soil‐level and row potassium treatments were about equally effective in supplying potassium for a corn‐soybean‐wheat‐hay rotation. Relative increases in corn and soybean yields due to potassium fertilization were inversely correlated with the amount of rainfall which occurred during the growing season.
