Choose the correct answer from the options given below
Match List-I with List-II
| List-I | List-II |
|---|---|
| (A) Alkalisation | (I) Low permeability |
| (B) Dispersed soil | (II) Increase in exchangeable sodium content |
| (C) CEC | (III) Degree of saturation |
| (D) ESP | (IV) Milliequivalents/100gm |
Choose the correct answer from the options given below
Show Hint
Sodic soils (ESP \( > \) 15%) suffer from clay dispersion and poor structure.
Adding gypsum (\( \text{CaSO}_4 \cdot 2\text{H}_2\text{O} \)) displaces the sodium with calcium, which helps flocculate the clay and restore soil permeability.
