Question

Solution
The quantum of water contained in the soil pores which cannot be extracted by gravity drainage is called (C) Hygroscopic water.
Hygroscopic water is a thin film of water that is tightly bound to soil particles and is unavailable to plants. It is held too tightly by the soil particles and cannot be extracted by the roots of plants. This water is held at very high tension and is usually absorbed from the atmosphere.
