Irrigation

hygroscopic water

Agriculture; Irrigation

Water that is strongly bound to the soil particles at suctions greater than 31 bars. This water cannot be used by plants. The suction limit is, again, approximate.

1. The rate of flow of a fluid through a unit cross-section of a porous mass under a unit hydraulic gradient, at a specified temperature (sometimes called unit of permeability, transmission constant ...

infiltration rate

Agriculture; Irrigation

Rate at which water can enter the soil often measured in units of depth per unit time. The term usually refers to water occurring as precipitation, but it is also applied to water flowing or ...

inflitration

Agriculture; Irrigation

The passage of water through the surface of the soil or the volume of water that passes into the soil profile over a unit irrigated area.

hydrologic cycle

Agriculture; Irrigation

The circulation of water from the sea through the atmosphere to the land and then, often with many delays, back to the sea or ocean. The water passes through various stages and processes, such as ...

intake rate

Agriculture; Irrigation

Rate at which water enters the soil after infiltration has decreased to a low and nearly constant value. This value should be used for sprinkler and drip irrigation system designs.

irrigation

Agriculture; Irrigation

Application of water by artificial means. Purposes for irrigating may include, but are not limited to, supplying evapotranspiration needs, leaching of salts, and environment control.
