Question

The characteristic of Saline-Alkali soil are

• A. $\text{pH} > 8.5$, $\text{EC} > 4 \text{ dSm}^{-1}$, $\text{ESP} > 15$
• B. $\text{pH} > 8.5$, $\text{ESP} < 15$, $\text{EC} > 4 \text{ dSm}^{-1}$
• C. $\text{pH} < 8.5$, $\text{ESP} > 15$, $\text{EC} < 4 \text{ dSm}^{-1}$
• D. $\text{pH} > 8.5$, $\text{ESP} > 15$, $\text{EC} < 4 \text{ dSm}^{-1}$

Hint:

Remember the diagnostic limits for Saline-Alkali (Saline-Sodic) soils:
- EC: $> 4\text{ dS/m}$
- ESP: $> 15\%$
- pH: Classically variable (typically $\ge 8.5$).
