The Soil Conservation Service has developed a model to evaluate the effect of various sprinkler irrigation systems with associated agronomic practices. Many researchers have dealt with various aspects of sprinkler and center pivot systems with their affect on the soil resource. Using this research and sprinkler data, a modified form of the Universal Soil Loss Equation (USLE) was adapted for irrigation precipitation. This provides a model to address the effects between various sprinkler irrigation packages. With USLE, comparison against various topographic, cultural, soil, and crop parameters can be evaluated with the systems to determine potential runoff and erosion.
