Soil health is an indicator of dynamic biological, chemical, and physical properties that supports diverse soil processes critical to productive, resilient, and sustainable landscapes.
Soil biology is soil life. The soil full of living roots, soil microbes invertebrates.
Soil chemistry determines availability of nutrients. Soil nutrients transform, and the soil supplies and retain nutrients.
Soil physics tells us about the structure of soil. Soil is made up of solid particles, air, and water.
