Question

Soil salinization is common in semi-arid region because

• A. Soil erosion occurs very frequently
• B. Leaching is not adequate
• C. Dense microbial flora
• D. All of the above

Answer 1

The correct option is B Leaching is not adequate

Soil salinization is the process of increasing the salt content in the soil. It is common in semi-arid regions because of inadequate leaching which leads to accumulation of salt below the root zone leading to salinization.

So, the correct answer is option B.
