Field moisture capacity
WebWhat is field capacity? Field water capacity is defined as “the content of water on a mass or volume basis remaining in a soil two or three days after having been wetted with water and after free drainage is negligible.” … WebThe top layer, with assumed 254 mm of water at field capacity, regulates the recharge to the underlying layer and evaporative loss from the system. Under moisture surplus condition, evaporation is at the potential rate, potential evapotranspiration (PET). Otherwise, it is a computed by using the Thornthwaite approach.
