- Sandy silt soil
- Clayey soil
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The soil with the highest water retention capacity is Clayey soil.
Additional Context:
- Clayey Soil Properties:
- Particle size: <0.002 mm (smallest among soil types)
- Surface area: High (increases water adhesion)
- Pore spaces: Numerous but very small
- Water Retention Mechanism:
- Capillary action in micro-pores
- Negative charge of clay particles attracts water molecules
- Comparison with Other Soils:
- Sandy (1): Large particles (0.05-2mm), drains quickly
- Loamy (2): Balanced mix but less retention than clay
- Sandy silt (3): Intermediate, moderately retains water
- Agricultural Implications:
- Clay soils require less frequent irrigation
- May need drainage systems to prevent waterlogging
Correct Answer: (4) Clayey soil.
