Question

The water available to all plants in the soil is

• A. hygroscopic water
• B. gravitational water
• C. capillary water
• D. chemically bound water

Answer 1

The correct option is C capillary water

The different forms of water in the soil are :
1. Gravitational water
2. Hygroscopic water
3. Chemically combined water
4. Capillary water.
Gravitational water goes down into the deeper layers of earth and is not available to the plants.
Hygroscopic water is present in the form of thin film around the soil particles and it is also not available to the plant.
The amount of water present in the chemical compounds which are present in the soil is called chemically combined water and is not available to the plants.
The only water which is available to the plants is capillary water. Capillary water makes up about 75% of the total water available to plants. It is held in the small pores of the soil.
