Specific gravity of soil used to get porosity

WebFor 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. WebUsually, particle density is expressed in units of grams per cubic centimeter (g/cm 3 ). An average value for particle density is 2.66 g/cm 3. This means that a soil particle that is 1 cubic centimeter in volume weighs 2.66 g. In comparison, water has a density of 1 g/cm 3, and organic matter has a density of 0.8 g/cm 3.
