Section 1 Soil three phases Constitution Soil density and bulk density (一) Soil density( or Particle density) Soil density is the density of the solid soil particles only; the measurement does not include water weight or pore (air)space. The dominant soil minerals-quartz, feldspars micas, and clay minerals-
