In modeling land surface processes, this is a parameter estimated as the water content of the soil a few days following a saturating rain when the water drainage rate has become less than some small value. Whatever the precise definition of this admittedly fuzzy concept may be, it is generally much less than the saturated water content of the soil. The field capacity is used, when subtracted from the soil water content at the wilting point, to ascertain the amount of water than can be stored in a soil. See Dickinson (1992).
The condition of a soil when it contains all the water retained after draining freely under gravity.
The maximum amount of water your particular soil will hold.
The amount of water remaining in a field soil that has been thoroughly wetted and drained until free drainage has practically ceased. The soil can no longer absorb additional moisture.
A measure of the maximum volume of water that a soil can hold by capillary action, i.e., against the pull of gravity.
is the amount of water in the soil after all free gravitational water has been removed (drained via gravity) and no additional water can be held in the soil.
Maximum water holding capacity of the soil which is usually measured in inches of water per inch of soil of soil depth.
The water content of the soil immediately after all 'free water' has been drained by the force of gravity (Hillel, 1980). Typical values range from 10-40 vol% with the lower range generally found in sandy soils and the upper range often associated with clay-type soils.
The soil-water storage capacity; the saturated soil profile after gravitational percolation ceases to flow.
Related Topics: [ drainage] The maximum water content of a soil when gravitational water is removed. The resulting moisture, less the amount remaining when the moisture level reaches the permanent wilting point, is available to support plant growth.
The amount of water the soil can hold once gravitational water has drained away; this water is mostly capillary water held to soil particles with at least 0.3 bars of suction.
The amount of water a soil can hold
The point at which all excess gravitational water has drained from a soil.
The percentage of water remaining in a soil after it has been saturated and after free drainage is negligible.
amount of moisture held by a soil after drainage following a water application. This figure may be stated as a percentage based on a dry weight basic or in inches per foot or centimeters per meter of moisture of depth.
When the soil particles are holding all the water they can and no drainage is occurring.
The maximum amount of water that the soil can store against for use by plants during the growing season.
The quantity of water held back by soil or rock against the pull of gravity when excess water has drained out of a saturated or near-saturated soil. It is sometimes limited to a certain drainage period (two or three days). Field capacity is thought to be the soil-moisture condition that will promote maximum plant growth, with transpiration occurring at the potential rate (i.e., transpiration is not limited by moisture availability.)
The capacity of soil to hold water at atmospheric pressure. It is measured by soil scientists as the ratio of the weight of water retained by the soil to the weight of the dry soil.
the percentage of water remaining in a soil two or three days after having been saturated and after drainage due to gravity has stopped.
The amount of water held in unsaturated soil pores after a period of free drainage.
the maximum amount of water that a soil can retain after excess water from saturated conditions has been drained by the force of gravity.
percentage of water remaining in the soil 2 or 3 days after the soil has been saturated and free drainage has practically ceaaed. The percentage may be expressed in terms of weight or volume.
The amount of water held in soil against the pull of gravity.
(FC): The water content, (%v), of the soil matrix approximating the water content of a saturated soil that has been allowed to freely drain. Estimated as a hydraulic tension of 33 kPa (.33 Bar) and dependant only on the soil texture and unaffected by salinity or gravel.
The percentage of water a soil retains against the action of gravity and typically is that remaining in a soil 2 to 3 days after having been saturated and free drainage has occurred. Estimated at -33 kPa water potential.
The point at which soil becomes saturated and cannot hold more rainfall. If drainage is good, this should rarely occur but if it is poor runoff and erosion may occur.
The state of saturated soil when all the soil moisture that is able to freely drain away has done so
The maximum quantity of water held by the vadose zone against the pull of gravity. Field capacity is dependent on the length of time the soil has been undergoing gravity drainage.
The amount of water held in the soil after the excess gravitational water has drained away and after the downward movement of water has materially decreased. cf. permanent wilting point.
The amount of water that soils can hold against the pull of gravity and that can be used by plants.
the amount of water remaining in a soil after the soil layer has been saturated and the free (drainable) water has been allowed to drain away (a day or two). Estimated at -33 kPa water potential.
The amount of water remaining in a soil when the downward water flow due to gravity becomes negligible. If a soil is saturated by rainfall or irrigation and then allowed to drain freely for twenty four hours, the soil is usually at field capacity. For most crops the field capacity is the ideal moisture level.
Following drainage in a soil, which is typically 1 - 3 days after rainfall, this is the amount of water that remains in the soil profile and is the commencing point for the available water capacity. It is the maximum amount of water that a soil can retain against the force of gravity.
Content of water, on a mass or volume basis, remaining in a soil after being saturated with water and after free drainage is negligible.
The amount of water left in the soil after it has been saturated and allowed to drain by gravity for 24 hours. See also detention storage, gravitational water, retention storage.
Field capacity is defined as the amount of water held in soil after excess water has drained away and the rate of downward movement has materially decreased, which usually takes place within 2 - 3 days after a rain or irrigation in pervious soils of uniform structure and texture. The term originated from Israelson and West (1922) and Frank Veihmeyer and Arthur Hendrickson (1931).
