Question

Identify the adverse effect(s) due to soil salinity or alkalinity or both:

• A. Low yields of crops
• B. Increased infiltration leading to waterlogging
• C. Poor quality of fodder
• D. Limited type of crops can be grown

Hint:

Soil salinity and alkalinity reduce crop yields and can make the soil unsuitable for many plants. It’s important to manage soil conditions to improve agricultural productivity.

Answer 1

The Correct Option is A, C, D

Soil salinity and alkalinity can have several adverse effects on agricultural productivity and the quality of land. Here’s how each option relates to these conditions:

(A) Low yields of crops: High salinity and alkalinity in soil can reduce the ability of plants to take up water and nutrients, leading to low crop yields.

(B) Increased infiltration leading to waterlogging: While waterlogging is a problem, it is more often associated with poor drainage rather than soil salinity or alkalinity.

(C) Poor quality of fodder: Saline or alkaline soils can affect the growth of plants that are used as fodder, resulting in poor quality.

(D) Limited type of crops can be grown: Saline and alkaline soils restrict the range of crops that can be successfully grown, making it difficult to grow a variety of crops.

Thus, the correct answers are: Low yields of crops, Poor quality of fodder, Limited type of crops can be grown.
