The pore space of soil is the portion occupied by air and water and it is determined largely by structural conditions. Sands have low pore space of about 30%, whereas clays may have as much as 50-60%. Although clays possess greater total porosity than the sands the pore spaces in the latter being individually larger are more conducive to good drainage and aeration. |
