Soil erosion is one of the major threats to the environment. Which of the following can help prevent soil erosion?

Correct option is A

The correct answer is (a) Contour Plowing.

Soil erosion is a significant environmental threat, leading to the loss of fertile topsoil, reduced agricultural productivity, and degradation of the ecosystem. Contour plowing is an effective method to combat soil erosion. It involves plowing along the contours of a slope rather than up and down. This technique helps in slowing down water runoff, preventing it from washing away the soil, and allowing more water to infiltrate into the ground.

Why Contour Plowing is Effective:

1. Reduces Water Runoff: By plowing along natural contours, water is slowed down, minimizing soil erosion.
2. Prevents Soil Loss: It helps retain topsoil, which is essential for fertile agricultural land.
3. Improves Water Absorption: The slowed runoff allows water to seep into the ground, benefiting crop growth.
4. Decreases the Risk of Landslides: On slopes, contour plowing reduces the pressure exerted by water, reducing the chance of landslides.
5. Sustainable Agriculture Practice: It is a recommended method for sustainable agriculture, conserving soil and water resources.

Information Booster:

● Soil erosion leads to loss of fertile topsoil and reduces land productivity.
● Contour plowing is highly effective on sloped lands to prevent soil erosion.
● It promotes better water conservation and enhances soil moisture for crops.
● Contour farming helps in sustaining agriculture by conserving soil.
● Preventing soil erosion is crucial for environmental conservation and sustainable agriculture.

Additional Knowledge:

• (Option a) Contour Plowing: Correct answer, as it prevents soil erosion by following the land's natural contours.
• (Option b) Grazing of cattle: Uncontrolled grazing by livestock can worsen soil erosion, as animals often trample and remove vegetation that holds soil together.
• (Option c) Poor Irrigation Practices: Poor irrigation, such as flooding, can lead to soil erosion by washing away the topsoil.
• (Option d) Over Farming: Excessive farming exhausts soil nutrients and makes the soil loose, increasing the risk of erosion
