Assertion: Arid soil is unsuitable for cultivation. It is true.
• Most desert soils are called Aridisols (dry soil).
• These are porous sandy soils with low nitrogenous matter and humus.
• These are saline in nature too.
Reason: Arid soil is generally sandy in texture and saline in nature. It restricts the filtration of water. Reason is True.
• Arid Soil is generally sandy and saline.
• Due to the dry climate, high temperature, evaporation is faster and the soil lacks humus and moisture.
• After proper irrigation these soils become cultivable as has been in the case of western Rajasthan.
Conclusion: Assertion is true, reason is true and reason is correct explanation of assertion.
Hence, the Correct Answer is A

Assertion and Reasoning
Assertion and reasoning questions are designed to test the ability of the candidate to think logically and to evaluate the given statement. In these types of questions, a statement of assertion is followed by a statement of reasoning. The candidate is required to examine both the statements and choose the correct option from the given alternatives.
Explanation
Assertion: Arid soil is unsuitable for cultivation.
Reason: Arid soil is generally sandy in texture and saline in nature. It restricts the filtration of water.
The correct option is A. If Both assertion and reason are true and reason is the correct explanation of assertion.
Explanation:
Arid soil is unsuitable for cultivation because of the following reasons:
1. Lack of water: Arid regions receive very little rainfall, which makes it difficult for crops to grow. The scanty rainfall results in the soil being dry and lacking in moisture, which is crucial for plant growth.
2. High salinity: Arid soil is salty due to the accumulation of salts over time. This makes it difficult for plants to absorb water and nutrients from the soil.
3. Sandy texture: Arid soil is generally sandy in texture, which makes it less fertile. Sandy soil does not retain water and nutrients, which are necessary for plant growth.
4. Low organic matter: Arid soil has low organic matter, which means it lacks the nutrients necessary for plant growth.
The reason given in the statement is correct as arid soil is generally sandy in texture and saline in nature. The high salt concentration in the soil makes it difficult for water to penetrate, restricting the filtration of water. Hence, option A is correct.
Conclusion
In assertion and reasoning questions, the candidate needs to evaluate both the statements carefully. The given statement is true, and the reason given for it is also correct. Arid soil is unsuitable for cultivation due to its sandy texture, high salinity, lack of water, and low organic matter.
