Question

Tilling enables the soil to take more gases and water. Justify

Answer 1

Tilling is a mechanical manipulation of soil. It enhances water infiltration by increasing the soil porosity, specifically large pores, that also stimulate the movement of gases through the soil. As a result, tilling facilitates the diffusion of water and gases between the soli layers. The presence of large pores in the soil also provides gas exchange by the mass flow that is more efficient than diffusion. As a result, tilling improves the penetration and transportation of water and gases in the soil.
