Field capacity - Wikipedia
WebField capacity is the amount of soil moisture or water content held in the soil after excess water has drained away and the rate of downward movement has decreased. This usually takes place 2–3 days after rain or irrigation in pervious soils of uniform structure and texture.
Understanding Soil Water Content and Thresholds for Irrigation ...
WebMost agricultural soils reach field capacity one to three days after an irrigation or rainfall event. At this threshold, typical VWC varies from 20 percent in sandy soils to 40 percent in clay soils (2.4 to 4.8 inches per foot). Typical value of …
Soil water – Introduction to Soil Science
WebField capacity is defined as the maximum amount of water that a soil can hold after gravitational drainage (Gardiner and Miller, 1998). Water is held with a tension of -0.1 to -0.3 bar (-10 to -30 kPa), and plants can easily pull it out of the system.

WebField capacity is the soil water content after the soil has been saturated and allowed to drain freely for about 24 to 48 hours. Free drainage occurs because of the force of gravity pulling on the water.

WebField capacity represents the soil water content retained against the force of gravity by matric forces (in micropores and mesopores) at tension of -0.033 MPa (Figure 2).

Field Water Capacity | SpringerLink
WebJan 1, 2014 · Field water capacity or field capacity (FC) is the upper limit of the available soil water (AW) reservoir, from which water can be released but not necessarily absorbed by plants, until the permanent wilting point (PWP) is reached.
5.7: Soil-Water Relations - Geosciences LibreTexts
WebJun 24, 2021 · Gravitational water represents the difference in soil moisture content between the saturation condition and field capacity. Gravitational water = soil moisture content at saturation - soil moisture content at field capacity. Water held within small soil pores by adhesion and cohesion is termed capillary water.
8.3 Field Capacity – Rain or Shine - OPEN OKSTATE
WebThe concept of field capacity has often been used in irrigation planning, crop modeling, and hydrologic modeling. Field capacity is thought to be the volumetric water content at which drainage effectively ceases. This hypothetical water content value is often incorrectly considered a property of the soil.
