Use of Iowa Phosphorus Index is required by Iowa Laws for planning the use of manure nutrients on agricultural crop lands. Producers required to complete a Comprehensive Nutrient Management Plan or a Manure Management Plan have requested assistance for implementation of Revised Universal Soil Loss Equation # 2 (RUSLE2) and the Iowa Phosphorus Index in their farming operations.
Over the last twenty-four months, 31 producers have requested assistance with implementation of RUSLE2 and Iowa Phosphorus Index. This has required an educational response to help individual producer seeking assistance on how to manage soil erosion on their fields, which tillage practice help conserve top soil, and what are critical areas in regards to resource conservation in their fields. This educational response has also included assisting several producers with RUSLE2, Iowa Phosphorus Index, and Nutrient Planning calculations for their respective operations.
Over 3,000 acres were impacted for soil erosion and over 15,000 acres were impacted for nutrient management when working with these 31 producers. By understanding, implementing, and improving resource management strategies, these producers were able to reduce soil loss from their fields by 1.1 tons per acre per year on an average basis. In addition, these producers were able to save over $25,000 in reduced fertilizer costs by implementing a better nutrient management and utilization plan.
