Soil Particle Analysis Procedure
Soil pore space relates to the size of soil particles. Soils with mostly clay-size particles have greater porosity (up to 50 percent), while soils dominated by large particles such as sand and gravel have a lower porosity (closer to 35 percent). The distribution of air and water in the soil pores also relates to the soil particle size.
