- Water activity is a better index for microbial growth than water content since microorganism only uses available water of the food sample. Some factors affecting the responses of microorganisms to water activity are the production of metabolites, taxonomic classification and solute concentration.
Soil moisture affects the soil biota in two ways. Biologically water is essential for life and for enzyme activity and metabolism and, is a solvent for biological nutrients and other chemicals. Physically, soil moisture affects soil temperature (water is good conductor of heat) and soil aeration. The degree at which soil pores are filled affects the movement and predation of microorganisms in soil.
