Question

In our country, large patches of forests are being cleared for the cultivation of crops. The environmental impact of such a practice will lead to

• A. Soil erosion
• B. Soil conservation
• C. Soil pollution
• D. Soil fertility

Answer 1

The correct option is A

Soil erosion

The correct option is A.

Explanation for the correct option:

Option A:

1. During this process, the soil pieces are loosened or washed away in valleys, oceans, rivers, streams, or remote locations.
2. This has gotten worse as a result of human activities like agriculture and forestry.
3. Soil erosion is a constant process that might occur quickly or slowly.
4. As a result, topsoil is continuously lost, ecological damage occurs, the soil collapses, etc.
5. The soil is at risk of erosion due to the construction of buildings and roadways.
6. For construction purposes, the forests and meadows are destroyed, exposing the soil and making it susceptible to erosion.
7. Techniques to prevent soil erosion:
   1. To prevent soil erosion on bare ground, plant trees.
   2. To stop the grass and plants beneath it from eroding, add mulch and rocks.

Explanation for the incorrect options:

Option B:

1. To stop soil degradation, a variety of strategies are used in conjunction.
2. To save soil, one must first approach it as a living ecosystem.
3. This calls for routinely replenishing the soil with organic materials.
4. Crop rotation, reduced tillage, mulching, cover crops, and cross-slope farming are some of these techniques.
5. farmers to improve soil structure, rooting depth, and organic matter content.

Option C:

1. When abnormally high amounts of harmful compounds are present in the soil, it is referred to as soil pollution.
2. Given the numerous health risks it contains, it is a severe environmental concern.
3. For instance, exposure to soil with high benzene concentrations increases the risk of developing leukemia.
4. Measures to prevent and stop soil pollution:
   1. Pesticide usage ought to be kept to a minimum.
   2. Waste should be disposed of in specially designated pits.

Option D:

1. The capacity of the soil to support plant growth and maximize crop yield is known as soil fertility.
2. This can be improved by adding organic and inorganic fertilizers to the soil.
3. Data from nuclear methods improve crop output and soil fertility while having little negative environmental impact.
4. The ability of soil to support plant growth by offering vital plant nutrients and desirable chemical, physical, and biological properties as a habitat for plant growth is known as soil fertility.
5. Plants contain the macronutrients nitrogen, phosphorus, and potassium, as well as sulfur, calcium, and magnesium.

Final answer: In our country, large patches of forest are being cleared for the cultivation of crops. The environmental impact of such a practice will lead to soil erosion.
