“What We Talk about When We Talk about Soil Health” with Dr. Ryan Stewart.
Soil health is an important topic for today’s scientists, but how do we quantify it, and when we talk about “healthy soils,” what do we even mean?
Dr. Ryan Stewart and his team set out to answer just that. Doing a meta-analysis on dozens of studies listed in The Soil Health Institute’s Research Landscape Tool, Ryan and his team compared different soil health indicators to determine what scientists are measuring, how they’re measuring it, and which are the most valuable in actually determining soil health.
Join us to learn:
- How measuring soil health is similar to measuring health in humans
- What kinds of soil health indicators scientists measure
- How these indicators can be grouped and compared across multiple studies
- Which indicators are the most helpful in measuring soil health
