WebThe bulk density of soil reflects the mass or weight of a certain volume of soil. Soil bulk density determines the infiltration, available water capacity, soil porosity, rooting depth/restrictions, soil microorganism activity, root proliferation, and nutrient availability. WebApr 7, 2016 · Bulk density is expressed as a ratio of grams per cubic centimeter (g cm −3 ). Since the mass of a cubic centimeter of water is about 1 g, the bulk density of water is said to be 1 g cm −3 or 1. Soil usually has a bulk density greater than water. For topsoils a value of 1.1–1.3 g cm −3 is about normal.
