  • Hydrology and Hydrography

The amount of moisture retained by a soil initially at a high water content, which is permitted to drain by gravity, for a specified period of time, usually 2-3 days.


As the water enters the soil, air is displaced and the surface soil "wets up" that is the soil pores are filled with water. Continued application will result in further downward movement and air replacement... the soil is said to be saturated with respect to water and is at its maximum retentive capacity.


Part of this coolness is due to the water-holding ability of the forest ecosystem.


field capacity: term also used in the field of agrometeorology.

  • Science du sol
  • Drainage et irrigation (Agriculture)
  • Hydrologie et hydrographie

Quantité d'eau retenue dans un sol après que l'eau de gravité s'est écoulée.


La capacité de rétention correspond sensiblement à la quantité maxima d'eau capillaire retenue par le sol.


Dans le sol, cette teneur en eau maximale se définit par la quantité d'eau, par unité de volume ou de masse, restant après ressuyage d'un sol initialement saturé d'eau, on l'appelle capacité au champ.
