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. WebWater content in me root zone can also be expressed by root zone depletion, D r, i.e., water shortage relative to field capacity. At field capacity, the root zone depletion is zero (D r = 0). When soil water is extracted by evapotranspiration, the depletion increases and stress will be induced when D r becomes equal to RAW. ir100/110v250wrh https://ohiodronellc.com
