Question

The moisture held by a well-drained soil against gravity drainage, by the force of surface tension between soil grains and water drops, is called:

• A. Field capacity water
• B. Hygroscopic water
• C. Capillary water
• D. Water of adhesion

Hint:

Capillary water is the most important form of soil moisture for plants as it is held in micropores and is readily available for absorption.

Answer 1

The Correct Option is C

Capillary water is the moisture retained in the pore spaces of soil due to surface tension. It is held against gravitational forces and is available for plant use, making it crucial for agricultural productivity.
