"Putting the Soil Health Principles to the Test in Iowa, USA" with Dr. Marshall McDaniel and Hillary Olson
Soil health principles can help guide farmers in best practices for long term soil health and improvement. However, it's important to test these principles across locations and contexts to see how their implementation is actually shaping soil health. In this episode, Marshall and Hillary join me to discuss testing the soil health principles in Iowa and how this might be expanded into further regions.
Tune in to learn:
· What the soil health principles are
· Which soil health indicators are fast or slow movers
· Why it's difficult to weight soil health principles
· What future research is yet to be done
