desiccation

[‚des·ə′kā·shən]
(hydrology)
The permanent decrease or disappearance of water from a region, caused by a decrease of rainfall, a failure to maintain irrigation, or deforestation or overcropping.
(science and technology)
Thorough removal of water from a substance, often with the use of a desiccant.

Desiccation

 

the preharvest drying of plants, which hastens their maturation and facilitates machine harvesting. Desiccation is carried out with the help of chemical substances, desiccants . It is most widespread in cotton cultivation. Desiccation of cotton resulting in the opening of as much as 60-75 percent of the bolls does not reduce either the quantity of raw cotton harvested or its quality. Desiccation is also being introduced in harvesting the seeds of horsebeans, legumes , and lupines, sugar beets, rice, wheat, and other crops.

desiccation

1. The use of a desiccant for drying.
2. The use of heated air to remove moisture, as from timber in a kiln.
