WebThis is the maximum amount of water that soil can store to be extracted by the plants. It is the water held between field capacity and permanent wilting point. The total available … WebWhen the soil is at or near field capacity, micropores in the soil are full of water and the macropores allow for the movement of oxygen. When a soil is above field capacity, the macropores fill with water and the soil is depleted of oxygen. When this happens, plant roots cannot get oxygen from the soil and microbial activity slows.

WebPermanent wilting point. A plant rooted in soil that is beyond the wilting point. Permanent wilting point ( PWP) or wilting point ( WP) is defined as the minimum amount of water in the soil that the plant requires not to wilt. If the soil water content decreases to this or any lower point a plant wilts and can no longer recover its turgidity ...
