WebThe amount of soil water available to plants is governed by the depth of soil that roots can explore (the root zone) and the nature of the soil material. Because the total and available moisture storage capacities are linked to porosity, the particle sizes (texture) and the arrangement of particles (structure) are the critical factors. WebSoil porosity values range from 0 to 1. Soils with a high bulk density have low total porosity because empty pores do not have any mass. When the bulk density is zero, porosity equals 1, meaning there are no particles. If the bulk density is equal to the particle density, then there are no pores and porosity is zero.
