Abstract
Yield responses of soybeans to phosphorus and potassium fertilizers have the reputation of being small and inconsistent unless the soil tests low to very low with respect to these elements. Consequently, soybean fertilization is commonly left to the residual effect of fertilization of other crops in the rotation such as corn. Field experiments were conducted with the general objective to investigate means whereby the magnitude and consistency of soybean responses to fertilization may be improved.
