Infiltration and permeability describe the manner by which water moves into and through soil. Water held in a soil is described by the term water content. Water content can be quantified on both a gravimetric (g water/g soil) and volumetric (ml water/ml soil) basis. The volumetric expression of water content is used most often..

For our ideal soil, one-half of it is solids, and one-half is pore space. Using our example of a 1 cm 3 volume, the ideal soil would have 0.5 cm 3 of pore space and 0.5 cm 3 of solids. Pore space filled with air weighs 0 g. Organic matter is a very small portion of the solids, so it is usually ignored in this calculation..
