Question

what are pore spaces​

Answer 1

Answer:

Hey!

The pore space of soil contains the liquid and gas phases of soil, i.e., everything but the solid phase that contains mainly minerals of varying sizes as well as organic compounds.

Answer 2

Answer:

1. Porosity or pore space refers to the volume of soil voids that can be filled by water and/or air. It is inversely related to bulk density. Porosity is calculated as a percentage of the soil volume: Bulk density x 100 = % solid space.
2. Soil porosity is important for many reasons. A primary reason is that soil pores contain the groundwater that many of us drink. Another important aspect of soil porosity concerns the oxygen found within these pore spaces. All plants need oxygen for respiration, so a well-aerated soil is important for growing crops.
3. Pore size is generally the distance between two opposite walls of the pore (diameter of cylindrical pores, width of slip-shaped pores).
