Question

The relationship between soil moisture potential and soil moisture content is generally known as

• A. Soil texture and soil moisture content
• B. Soil structure and soil moisture content
• C. Available soil moisture and soil moisture content
• D. Soil moisture tension and soil moisture content

Hint:

Soil moisture characteristic curve:
- Relates water content to soil water potential.
- Also called soil water retention curve.
- Used to estimate plant available water.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
This question tests knowledge of soil moisture characteristics.

Step 2: Detailed Explanation:
The relationship between soil moisture potential (tension) and soil moisture content is known as the soil moisture characteristic curve (D).
It is also called the soil water retention curve.
It describes how much water is held at different tensions.
Other options:
- Soil texture and soil moisture content (A): Texture affects moisture content.
- Soil structure and soil moisture content (B): Structure affects moisture content.
- Available soil moisture and soil moisture content (C): Available moisture is a range.
Thus, the relationship is between soil moisture tension and content.

Step 3: Final Answer:
Thus, the relationship is between soil moisture tension and soil moisture content, which corresponds to option (D).
