Soil health indicator: Depth of top soil in cm
A crude measure of soil health. Indicates the extent to which the soil has been developed by biological action. Typically top soil (or upper portion of the soil profile) will differ in appearance from the subsoil (parent material) and often be darker or more textured. The deeper the top soil, the further roots can grow and the more water and nutrients will be available.
