Plant Available Water, is key to determining potential crop yield. It’s also the basis for sowing decisions and fertiliser applications. Many things affect how much stored soil water is available, rainfall before and during the growing season, infiltration, evaporation and transpiration. And then there’s Plant Available Water Capacity, which is the total amount of water a soil can store and release to a crop which differs depending on the crop.
