“Addressing conservation practice limitations and trade-offs for reducing phosphorus loss from agricultural fields” with Dr. Pete Kleinman, Research Leader, USDA, and Dr. Deanna Osmond, Professor, North Carolina State University.

Conservation practices are important techniques that help us move towards a more sustainable planet. But when these tools are applied without proper testing and a holistic point of view, they can sometimes cause unintended consequences or tradeoffs that affect the surrounding environment. This episode, Pete and Deanna discuss common tradeoffs that can impact tools that manage Phosphorus and how to avoid these potential pitfalls.

Tune in to learn:

·         What the acronym ACT stands for when talking about nutrient management

·         What mechanisms turn phosphorus sinks into sources

·         Some real-world examples of tradeoffs at play

·         How to avoid some common tradeoffs
