Plant available water kpa
WebAvailable water is the difference between field capacity which is the maximum amount of water the soil can hold and wilting point where the plant can no longer extract water from the soil. Water holding capacity is the total amount of water a soil can hold at field capacity. Sandy soils tend to have low water storage capacity.
