capillary action
capillary action(capillarity) The process by which soil moisture may move in any direction through the fine (i.e. capillary) pores of the soil, under the influence of surface-tension forces between the water and individual soil particles. Soil moisture in this state is known as capillary moisture. It exists as a film or skin of moisture on the soil particles, and may be drawn above the water-table by capillary action and into the plant roots by the process of osmosis. ‘Capillary conductivity’ is now obsolete in US terminology.

capillary action
capillary action (capillarity) The process by which soil moisture may move in any direction through the fine (i.e. capillary) pores of the soil, under the influence of surface tension forces between the water and the soil particles. It is analogous to the rise of water in a cylindrical glass capillary tube whose end is placed in a bath of water in the laboratory, except that the pores of the soil are neither cylindrical, nor smooth-walled, nor clean. See also CAPILLARY MOISTURE.
