	A porous soil is a soil of usually granular composition that is full of tiny openings or channel way that is able to be filled (permeated) by water or air.

A porous soil (or growing medium) is a soil that allows water and air to seep (or rise) thought it ensuring a good drainage and aeration. Compaction make a soil less porous. Hence the porosity is the measure of the amount of liquid or gas that may be absorbed or yielded by a particular soil or formation. Water cannot, by definition, travel through non-porous (impermeable) layers.
