Jamie Patton, Outreach Specialist – UW-Madison Nutrient and Pest Management Program

Can We Move Past 35%? Increasing Wisconsin’s Cropland Acres Covered by a Nutrient Management Plan

Dr. Patton is an Outreach Specialist for the Nutrient and Pest Management Program at UW-Madison. She provides support to farmers, agronomists, and agency and industry professionals on nutrient and pest management to improve water quality while protecting farm profitability. Dr. Patton’s key programming includes nutrient management in northeast Wisconsin while also assisting with statewide research and outreach on soil heath, soil fertility and cover crops. Her poster focuses on the development of targeted educational initiatives to address the stagnating cropland acres covered by Nutrient Management Plans.

Chelsea Zegler, Ag & Water Quality Outreach Specialist –
UW-Madison Extension

Twenty Years of Discovery Farms Edge of Field Monitoring Indicate Runoff from Frozen and Non-frozen Ground Influence Type of Phosphorus Loss and Effective Agricultural Mitigation Strategies

Chelsea Zegler currently serves as an Agriculture Water Quality Outreach Specialist for UW-Madison Extension. She received a Master’s in Agroecology from UW-Madison, where she focused on forage production and soil health on dairies across the state. Her current work is centered around educating stakeholders on how conservation practices influence phosphorus and nitrogen loss dynamics. Her poster focuses on over 200 site-years of edge-of-field data to better understand the surface water quality impacts of agricultural practices.

Ellen Albright, Postdoctoral Researcher – Center for Limnology, UW-Madison

Internal Phosphorus Loading in Wisconsin Lakes and Reservoirs: Perspectives and Management Considerations from a Global Synthesis

Dr. Albright is a Postdoctoral Researcher at UW-Madison’s Center for Limnology. She is an ecosystem ecologist and biogeochemist studying how inland waters respond to stressors such as nutrient enrichment and climate change. Dr. Albright’s research is inspired by her conviction that everyone deserves access to safe drinking water and that our freshwater resources are a precious gift. Her poster focuses on internal phosphorus loading in Wisconsin lakes and reservoirs as it relates to phosphorus reduction and management.
