Question

In a field capacity, the soil contains

• A. Capillary and gravitational water
• B. Capillary and runway water
• C. Hygroscopic and capillary water
• D. Hygroscopic, capillary and bound water

Answer 1

The correct option is D Hygroscopic, capillary and bound water

The water content remaining in the soil after surface runoff and percolation of water to the water table is called as the field capacity. It consists of water readily available to plants (capillary water) as well as water, which is not available to plants (hygroscopic water and bound water).

Hygroscopic water is present as a thin film around the soil particles and is not available to plants. Bound water refers to the water, which is chemically bound to the mineral elements present in the soil. It is not available to the plants.

So, the correct answer is option D.
