Abstract: Agriculturists make daily decisions on the inputs of land, labor, capital, and management skills for their enterprise. However, decisions on fertilizer use are different from many other crop production inputs because of the choice of rates. Within the rationality of the decision-making process on fertilizer use, availability of resources and aversion to risk should be considered. The “minimum rate” of fertilizer is that rate which gives the greatest return per unit of fertilizer and application cost. Long-term investments in soil fertility practices, such as liming acid soils or high rates of fertilizer sulfur (S) providing residual effects must be considered in light of a real or individual discounting rate. Information on yield response of crops to fertilizer S and production economics lead to procedures is available to estimate economic optimum rates of fertilizer S, which produces maximum net return per unit land area.
