Minnesota: Optimal Soil Phosphorus, Potassium Levels – Podcast

In this episode of the Nutrient Management Podcast, three U of M researchers discuss optimal phosphorus and potassium levels in the soil.

What are some key takeaways that growers should know about interpreting soil tests? Environmentally, what is the threshold at which we should avoid applications to prevent significant nutrient loss? Is there really an optimal soil test level that farmers should shoot for?

Thank you to Minnesota’s Agricultural Fertilizer Research and Education Council (AFREC) for supporting the podcast.
