Question

Soil water available to roots is

(a) surface water

(b) hygroscopic water

(c) gravitational water

(d) capillary water.

Answer 1

Answer: Th soil water which is available for the plant is capillary water as it exists between soil particles in small capillary pores.

While The hygroscopic water will not available for plants as it firmly associated with soil particles.

The gravitational water also not available for plants as it percolates deep into the ground (beyond root system) water table due gravitational forces.

And the surface water which is present above ground and will be available to plants when it becomes capillary water after reaching capillary pores.
