Mississippi Phosphorus Index (MS-PI)
The PI for Mississippi (MS-ECS-TN05) is the NRCS approved nutrient risk assessment for phosphorus. The tool is used to assess the site and management practices for potential risk of phosphorus movement to water bodies. The PI uses specific field features and management practices to obtain an overall rating for each field. Mississippi uses a tool that considers transport characteristics such as soil erosion and soil runoff class; distance water, and source characteristics which are weighed according to their influence toward phosphorus movement.

The Revised Universal Soil Loss Equation 2 (RUSLE2) estimates soil loss from rill and interrill erosion caused by rainfall on cropland.
