Phosphorus Management Lessons Learned from the Field

Management of phosphorus in agriculture continues to challenge the sustainability of animal feeding operations. Three Extension and research leaders for phosphorus management issues will share their experience with us on critical lessons learned about phosphorus management.
  • Phosphorus and Soil Health Management: Are They Compatible? Soil health has gained widespread attention in conservation communities due to its many purported benefits, including claims that implementation will improve water quality by curtailing runoff losses of nutrients such as phosphorus (P). However, a review of the existing literature points to well established findings suggests trade-offs. This summary will describe those trade-offs and important management strategies for minimizing those trade-offs.
  • Arkansas Discovery Farm Experience for Managing P in Poultry. The Arkansas Discovery Farm Program is a public-private partnership between the University of Arkansas System Division of Agriculture and private landowners. The program engages farmers, works with them on-farm and within their management system to develop solutions to water quality and other natural resource issues. The program will focus on solutions for managing phosphorus in poultry systems.
  • Field Experiences with Manure P - A Lake Erie Basin Perspective. Agricultural practices are a significant contributor to algae blooms in Lake Erie. Kevin King will summarize field experiences and lessons learned for mitigation of phosphorus movement from land application sites and their value for future mitigation of Lake Erie’s water quality challenges.
An application for continuing education credit for Certified Crop Advisors (CCAs) and members of the American Registry of Professional Animal Scientists (ARPAS) will be submitted.

Presenters for this webinar include:
  • Deanna Osmond, North Carolina State University
  • Kevin King, USDA-ARS
  • Mike Daniels, University of Arkansas
  • Rick Koelsch, University of Nebraska - Lincoln (moderator)
Handouts (PDF format) will be available the day of the webinar at the live webinar information page.

About the Extension Foundation

The Extension Foundation was formed in 2006 by Extension Directors and Administrators. Today, the Foundation partners with Cooperative Extension through liaison roles and a formal plan of work with the Extension Committee on Organization and Policy (ECOP) to increase system capacity while providing programmatic services, and helping Extension programs scale and investigate new methods and models for implementing programs. The Foundation provides professional development to Cooperative Extension professionals and offers exclusive services to its members. In 2020 and 2021, the Extension Foundation has awarded 85% of its direct funding back to the Cooperative Extension System, 100% of funds are used to support Cooperative Extension initiatives.
