Unsaturated zone includes soil water zone, intermediate zone and capillary fringe
Most terrestrial plants extract water from the vadose zone. Plants wilt when soils become too dry because the forces holding the water in the soil are too great to allow the plants access to the water
the capillary fringe is a saturated zone above the water table where water is affected by capillary forces.
The uppermost belt, or belt of soil water, is that part of the lithosphere immediately below the surface, from which water is discharged into the atmosphere in perceptible quantities by the action of plants or by soil evaporation.
