Question

The pF curve is same as:

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

Hint:

Important pF values to remember:
- Field Capacity: \( \text{pF } 2.53 \) (approx. \( -0.33 \text{ bar} \))
- Permanent Wilting Point: \( \text{pF } 4.18 \) (approx. \( -15 \text{ bar} \))
- Hygroscopic Coefficient: \( \text{pF } 4.50 \) (approx. \( -31 \text{ bar} \))
- Oven Dry: \( \text{pF } 7.00 \) (approx. \( -10,000 \text{ bar} \))

Answer 1

The Correct Option is D
