Detailed explanation-1: -The volume of soil not occupied by solids is the pore space or porosity (PS) and is defined as: PS = (1-(BD/PD))100. example: assuming BD = 1.38, PD = 2.65; PS = (1-(1.38/2.65))100 = 48%
Detailed explanation-2: -Ideally, silt loam has 50 percent pore space and a bulk density of 1.33 g/cm3. Loose, well-aggregated, porous soils and soils high in content of organic matter generally have lower bulk density.
Detailed explanation-3: -Particle Density = mass of dry soil / volume of soil. particles only (air removed) (g/cm3) This value will always be less than or equal to 1. Bulk Density: Mass of dry soil = 395 g. Total soil volume = 300 cm3. Particle Density: Mass of dry soil = 25.1 g. Porosity: Using these values in the equation for.
