Clay type, organic content, and soil structure also influence soil water retention. The maximum amount of water that a given soil can retain is called field capacity, whereas a soil so dry that plants cannot liberate the remaining moisture from the soil particles is said to be at wilting point.
In the past 100 years, many laboratory methods have been developed around the world to determine soil water holding capacity. These methods use a variety of special apparatus to determine how much water a soil will hold under various conditions. Most of theses methods start with a water saturated soil sample.
