Soil Moisture
The water contained in the pore space of the unsaturated zone.

soil moisture tension
In soils partially saturated with water there is moisture tension, which is equal in magnitude but opposite in sign to the soil water pressure.
Soil moisture: Water contained in the aeration or unsaturated zone.
Sole source aquifer: An aquifer that supplies 50% or more of the drinking water of an area.
soil moisture content The portion of water in a soil that can be readily absorbed by plant roots. It is the amount of water released between in situ field capacity and the permanent wilting point.
WATER UPTAKE - SOIL MOISTURE
Just as a pressure chamber can be used to measure a plant's water potential, a tensiometer can be used to measure soil water potential.
It is a major factor in determining climate through its influence on surface vegetation, the clouds, snow and ice, and soil moisture.
The rate of infiltration changes dramatically as soil moisture content changes.
Resistance block: Type of soil moisture probe used to monitor soil moisture conditions to help determine when water should be applied.
Resolution: The breaking of an emulsion into its individual components.
Groundwater - Water that is contained within the ground of the Earth, such as in soil moisture or dew from plants. It makes up about 20 percent of the world's fresh water supply, and is highly subject to pollution.
