Answer:
Sandy soil
Step-by-step explanation:
Sandy soil has the greatest permeability of all soil types. It has a high amount of pore space and grain size.
Permeability is the ability of fluids to pass between the grains of a substance, here soil. It is usually a function of the size of the pore spaces and the grain size.
- Sandy soils are usually made up of particles with sand-sized shapes and dimension.
- They have bigger and finer grains with little to no cement.
- This allows for a high level of permeability with no impediment to flow.
- Clay soil has very fine grain and with very low permeability.
- Silty soils have fair enough permeability and the permeability of loam straddles between that of sand and clay.
Permeability is very important for determining the quality of soils.
