A thin film of water, held by the soil particles, under the influence of internal attractive forces, is called which of the following water?
Options
(a) capillary
(b) combined
(c) hygroscopic
(d) gravitational
Correct Answer:
hygroscopic
Explanation:
Hygroscopic water is the water that occurs in the form of thin film on the soil particles and is not available to the plants. Capillary water is the free water which due to the action of gravity moves downwards into the soil until it reaches the water table. Water fills the spaces between non colloidal soil particles and forms films around them . This is the only available water to the plants. Combined water is that water which is chemically bound with soil materials.
