From the University of Wisconsin Extension
In this video, Hava Blair, researcher, UW–Madison Department of Soil and Environmental Sciences, presents an in-depth overview of the Wisconsin Phosphorus Index (P Index), a modeling tool used to estimate phosphorus runoff from agricultural fields to nearby surface waters. Integrated into the SNAPPlus nutrient management planning software, the P Index helps farmers, agronomists, and conservation professionals assess phosphorus loss risk based on field management practices, soil characteristics, and landscape features. Hava explains how the model works, recent updates, and how it supports nutrient planning, conservation efforts, and water quality protection. The presentation also highlights how the model is validated using real-world data and used in various decision-support tools across Wisconsin. — At University of Wisconsin–Madison Division of Extension, we are working to integrate accessibility into our web, video, and audio content.
