Soil biological properties, unlike chemical and physical properties, are difficult to define. Various sources provide different lists of what comprises soil biological properties, ranging from listing only soil biota and microorganisms, to lists that include biological processes such as respiration, nutrient cycling, mineralization, and organic matter cycling.

We've chosen to list only soil biota and microorganisms as soil biological properties, but we provide a discussion of the processes affected by soil organisms and methods for measuring these processes. We include a discussion of effects of human activities, discussion of stormwater applications, and links to related topics, including information on sampling, testing, and soil health assessments.
