Question

The pF curve is same as

• A. Moisture - density relation
• B. Soil temperature - water relation
• C. Soil pH- base saturation relation
• D. Soil water content - matric potential relation

Hint:

Key pF values: - $pF = 0$: Saturation ($1\text{ cm}$ head) - $pF = 54$: Field Capacity ($346\text{ cm}$ head or $1/3\text{ bar}$) - $pF = 18$: Permanent Wilting Point ($15,848\text{ cm}$ head or $15\text{ bar}$) - $pF = 7.0$: Oven-dry soil ($10,000,000\text{ cm}$ head or $10,000\text{ bar}$)

Answer 1

The Correct Option is D
