Question

Which of the following practices is most effective in preventing soil erosion?

• A. Mulching
• B. Monoculture farming
• C. Ploughing
• D. Trickle drip irrigation

Hint:

Mulching is one of the best ways to protect the soil from erosion, as it helps maintain soil moisture, provides nutrients, and reduces the impact of rainfall.

Answer 1

The Correct Option is A

Step 1: Understanding soil erosion.
Soil erosion is the removal of the topsoil layer due to factors like wind, water, and human activity. Effective practices aim to reduce the movement of soil and protect the soil from being washed or blown away. Step 2: Analyzing the options.

• (A) Mulching: Correct. Mulching is a highly effective method for preventing soil erosion. It involves covering the soil surface with organic or inorganic materials, which helps retain moisture, protect the soil from wind and water, and reduce soil erosion.
• (B) Monoculture farming: Incorrect. Monoculture farming involves growing one type of crop in a field, which can lead to soil depletion and increased erosion due to lack of plant diversity and root structure.
• (C) Ploughing: Incorrect. While ploughing can help prepare the soil for planting, improper ploughing techniques can contribute to soil erosion by loosening the topsoil.
• (D) Trickle drip irrigation: Incorrect. While drip irrigation conserves water, it does not directly address soil erosion, although it may help with moisture retention.

Step 3: Conclusion.
Therefore, the correct answer is (A) Mulching, as it is the most effective practice to prevent soil erosion. Final Answer:} Mulching.
