Question

In soil, water available for plants is

• A. Capillary water
• B. Hygroscopic water
• C. Gravitational water
• D. Chemically bound water

Answer 1

Answer: (A)

Capillary water

• Capillary water is present in the capillary spaces and this water is easily available to plant roots.
• Hygroscopic water is present as a thin film around soil particles and is not available to plant roots.
• Gravitational water is the water that seeps down to the water table under the influence of gravity.
• Chemically bound water is the water present in minerals and chemical compounds as their constituent.
• Both gravitational and chemically bound water is not available to plants.

So, the correct answer is 'Capillary water'.
