Available Water Capacity (AWC)

Available water capacity (AWC) is the amount of water that soil can store and make available to plants after excess water has drained. It is the difference between field capacity (the maximum amount of water soil can hold) and the permanent wilting point (where plants can no longer extract water). AWC is critical for understanding soil moisture and irrigation needs, helping growers ensure plants have adequate water for optimal growth.
