A phosphorus soil test interpretation for corn zea mays grown on acid soils varying in crystalline clay content



A phosphorus soil test interpretation for corn zea mays grown on acid soils varying in crystalline clay content



Communications in Soil Science & Plant Analysis 15(12): 1481-1492



Although there is considerable knowledge about P sorption in relation to soil properties, little of this information has been applied to the refinement of P soil test interpretations. Perhaps the most important soil property, and one that could be readily incorporated, is clay content. Corn was grown in residual P studies on 2 Ultisols that differed in clay content. Yield was first expressed as an exponential function of soil test P concentration, then the P concentration replaced with the rate of P required to maintain a given soil test P level for one year. Net income was computed from the yield, price of corn, rate of fertilizer and fertilizer cost. When net income was maximized, the optimum P rate for each soil was calculated in relation to the initial soil P concentration. These relationships were quite linear and differed markedly between soils due to clay content. A continuous function was then developed to express the optimum P rate for soils of any clay content and P concentration.
