(C) The amount of water retained by a unit weight of undisturbed soil after complete drainage under gravity is known as $Field \ capacity$. When soil is thoroughly wetted and allowed to drain,the water that moves downward due to gravity is called $Gravitational \ water$. Once the downward movement stops,the water held in the soil pores against gravity by capillary forces is known as $Capillary \ water$. The total water content remaining in the soil at this point is defined as the $Field \ capacity$ of the soil.

An area of soil is thoroughly wetted and allowed to drain until capillary movement of water stops. The water content of the soil at this stage provides an estimate of its:
