Difference between percolation and permeablity.

1.	Difference between percolation and permeablity.
Answer» The movement of water through a column of soil is called percolation. Percolation is important for two reasons. First, percolating water is the only source of recharge of ground water which can again be used through well for irrigation. Second, percolating waters carry plant nutrients down and often out of reach of plant roots (leaching). Percolation is dependent on rainfall. Permeability indicates the relative ease of movement of water within the soil. The characteristics that determine how fast air and water move through the soil is known as permeability. The term hydraulic conductivity is also used which refers to the readiness with which a soil transmits fluids through it.
