The overall assessment of soil health and biology is derived from the Haney test, developed by Dr. Rick Haney, USDA ARS. These mea- sured indicators of soil health can give inference on next steps to improve soil health.
Soil Microbial Activity The Solvita 1-day CO2-C test is performed.
WaterExtractableOrganicCarbonandNitrogen(WEOCandWEON WEOC and WEON represent the available nutrients (mineraliza- tion) in the soil that feed the microbes.
B. Method 2 : The Standard Soil Health Analysis Package of the Comprehensive Assessment of Soil Health (CASH) from Cornell University.
The test includes Soil pH, Organic Matter, Modified Morgan Extracta- ble P, K, micronutrients, Soil Texture, Active Carbon, Wet Aggregate Stability,Soil Respiration, Autoclave-Citrate Extractable (ACE) Protein Test,Available Water Capacity. The test measures indicators of the water cycle including wet aggregate stability and available water capacity, water infiltration. Minimum Cash Scores are 60 points, optimal soil structure and function correlates with scores above 80 points.
Haney Soil Health Calculation (for more information, visit: ) Soil health calculations can range from 0-50. Generally, soil health scores should be above 7.
