Soil factors, however, exert considerable control as well. The presence or absence of oxygen, more than any other single factor, determines the rate and end products. The oxygen status of the soil is a function of soil porosity, and properties that favor rapid transmission of water also favor oxygen movement unless the soil is completely saturated.
