Soil water storage formula
http://bettersoils.soilwater.com.au/module5/5_1.htm WebThe gravimetric water content is the mass of water per unit mass of dry (or wet) soil. The volumetric water content is equal to the gravimetric water content times the soil's bulk density (on a dry soil basis). Factors that affect the soil water storage are: Total Porosity or Void Space. Pore-size and Distribution and Connectivity.
