The water contained in the pore space of the unsaturated zone.
Water diffused in the soil, the upper part of the zone of aeration from which water is discharged by the transpiration of plants or by soil evaporation. See Field-moisture capacity and Field-moisture deficiency.
Moisture contained in the soil above the water table, including water vapor which is present in the soil pores. In some cases this term refers strictly to the humidity contained in the root zone of plants.
Water contained in the aeration or unsaturated zone.
The water content stored in soil.
The moisture content of soils is generally as the percentage ratio of the mass of water to that of dry soil, but may be expressed also in terms of inches of water per given depth of soil.
Water diffused in the soil and remaining as a measurable quantity, as the volume of water divided by the total volume.
the water contained in the pore spaces in the unsaturated zone.
Underground water that wets the surface of the mineral grains and organic material making up soil, but lies above the water table.
Water stored in or at the continental surface and available for evaporation. In IPCC 1990 a single store (or bucket) was commonly used in climate modes. Today's models which incorporate canopy and soil process view soil moisture as the amount held in excess of plant "wilting point." (IPCC)
Water diffused in the upper part of the soil mantle that is lost by the transpiration of plants or by soil evaporation.
The total amount of water, including the water vapor, in unsaturated soil.
Soil moisture is the amount of water present in the soil.
