Question

Identify the INCORRECT statement about water in the soil.

• A. Water present in the form of hydrated oxides of silicon and aluminium is called combined water.
• B. The hygroscopic and combined water is available to the plants for absorption.
• C. Water held between small, non-colloidal soil particles is called capillary water.
• D. Water which is held very tightly around soil particles by adhesive forces is called hygroscopic water.

Hint:

Only capillary water is considered plant-available soil water.

Answer 1

The Correct Option is B

Step 1: Understanding types of soil water.
Soil water exists in different forms such as gravitational, capillary, hygroscopic, and combined water.
Step 2: Availability to plants.
Only capillary water is available to plants. Hygroscopic and combined water are held too tightly to be absorbed by plant roots.
Step 3: Analysis of options.
(A) Correct statement.
(B) Incorrect — hygroscopic and combined water are not available to plants.
(C) Correct statement.
(D) Correct statement.
Step 4: Conclusion.
The incorrect statement is option (B).
