Measuring Soil Health

The Soil Health Institute and Soil Health Partnership have endorsed a number of soil health measurements. Examples of the specific Tier 1 measures include nutrient levels, organic carbon, pH and available water-holding capacity. Testing soil on a regular basis and using these indicators can help you best manage your crop and soil.

For more information on soil health metrics, visit the Soil Health Institute website.
