Attempt this previous-year question. The correct option stays hidden until you choose.
With reference to agricultural soils, consider the following statements :
1. The high content of organic matter in soil drastically reduces its water holding capacity.
2. Soil does not play any role in the sulphur cycle.
3. Irrigation over a period of time can contribute to the salinization of some agricultural lands.
Which of the statements given above is/are correct?
Pick an option to check yourself.
• Correct Answer: B
• Irrigation water leaves dissolved salts as it evaporates; over time, without drainage, this causes salinization.
• Organic matter increases water-holding capacity; soil microorganisms drive sulphur mineralization, so soil plays a vital role in the sulphur cycle.
