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.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content.

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.
