Description: ABSTRACT: A procedure to estimate the center pivot maximum application rate, based on equipment and soil characteristic is presented. It was developed to minimize the surface runoff. To achieve this objective, the Green and Ampt (GA) infiltration equation was modified to include surface sealing and surface storage. The highest application rate is determined by solving a system of equations which incout to application rate and its derivative and the GA and its derivative. Sensitivit analysis showed that the procedure represented adequately the variation in the main parameters that interfere in the value of the maximum application rate. This methodology can be used to desing the optimum center pivot irrigation system for given combination of soil, climate cropping pattern, and tillage practice. It can also be used to estimate the maximum aplication rate during irrigation for specific patches wthin the irrigated area
