Descriptive terms of water availability are: saturation, field capacity, wilting point, and hygroscopic coefficient. Although there is some water chemically bound to minerals in soils, the water of significance to us is found in the soil's pore space.
Which soil has more available water, one at field capacity or one at the hygroscopic coefficient?
