Unformatted text preview: Pores ~50% +/- Air, Water So soil bulk density should be roughly ½ particle density Remember, soil is roughly: Bulk density is the density of the (bulk or whole) soil, it includes the solids (Vs) and the pores (Vp). Db = Ms/Vt = ODwt/Vt = ODwt/(Vs + Vp) The bulk density of an ideal soil (50% pore space) would be equal to 1/2 that of the soil solids. (2.65 g/cm 3 x 0.5 = 1.33 g/cm 3 ) (Volumes: Vt = total soil; Vs = solids; Vp = pores) To calculate you need a known vol. and mass of OD soil. BULK DENSITY (Db)...
