Question

Which of the following types of soil water can be included under echard?

• A. Gravitational water
• B. Capillary water
• C. Hygroscopic water
• D. Both a and c

Answer 1

The correct option is D Both a and c

Soil water can be divided into 3 types- hygroscopic water, gravitational water and capillary water.
Hygroscopic water forms a thin film around the soil particles by adhering to them. This water is unavailable to plants.
Gravitational water seeps through the soil due to gravity. It drains into the water table. Very little amount of this water is available to plants.
Both hygroscopic water and gravitational water come under echard.
Capillary water is held in the micropores of the soil. It is the main water available to the plants. It comes under chresard.
