The Cornell Soil Health Testing Laboratory is the home of the Comprehensive Assessment of Soil Health (CASH):
The Comprehensive Assessment of Soil Health is designed for farmers, gardeners, landscape managers and researchers who want to go beyond simply testing the nutrient levels of their soils. It is the first commercially-available laboratory soil health test that provides standardized, field-specific information on important constraints in soil biological and physical processes, in addition to standard nutrient analysis.
The Assessment is regarded as a key tool for soil health measurement by several national initiatives, including Soil Renaissance, the Soil Health Partnership, and the USDA-NRCS Soil Health Division. We have conducted over 10,000 soil health package analyses since its rollout in 2006. Half were for commercial customers. In addition to the laboratory results for each sample, we have developed a soil health management planning framework included with the sample assessment results to help you focus management changes where they will be most effective in improving your soil.
The assessment’s indicators and management strategies for improving soil health are also detailed in the Comprehensive Assessment of Soil Health Training Manual, available free online.
