Which method of soil conservation involves planting trees and shrubs along the contours of a slope to reduce erosion?

  1. Contour Farming

  2. Strip Cropping

  3. Terracing

  4. Windbreaks


Correct Option: A
Explanation:

Contour farming is a method of soil conservation that involves planting crops along the contours of a slope, rather than up and down the slope. This helps to reduce erosion by slowing down the flow of water and preventing it from carrying away soil particles.

What is the practice of leaving crop residues on the field after harvest to protect the soil from erosion and improve soil health called?

  1. Mulching

  2. Cover Cropping

  3. Contour Farming

  4. Terracing


Correct Option: A
Explanation:

Mulching is the practice of leaving crop residues, such as straw, leaves, or compost, on the field after harvest. This helps to protect the soil from erosion by reducing the impact of raindrops and wind, and it also improves soil health by adding organic matter and nutrients.

Which method of soil conservation involves planting different crops in alternating strips to reduce erosion and improve soil fertility?

  1. Contour Farming

  2. Strip Cropping

  3. Terracing

  4. Windbreaks


Correct Option: B
Explanation:

Strip cropping is a method of soil conservation that involves planting different crops in alternating strips. This helps to reduce erosion by slowing down the flow of water and preventing it from carrying away soil particles. It also helps to improve soil fertility by diversifying the crops grown and reducing the risk of pests and diseases.

What is the practice of building earthen embankments or ridges along the contours of a slope to reduce erosion and conserve water called?

  1. Contour Farming

  2. Strip Cropping

  3. Terracing

  4. Windbreaks


Correct Option: C
Explanation:

Terracing is the practice of building earthen embankments or ridges along the contours of a slope. This helps to reduce erosion by slowing down the flow of water and preventing it from carrying away soil particles. It also helps to conserve water by creating level areas where water can be stored and used for irrigation.

Which method of soil conservation involves planting trees and shrubs in rows perpendicular to the prevailing wind direction to reduce wind erosion?

  1. Contour Farming

  2. Strip Cropping

  3. Terracing

  4. Windbreaks


Correct Option: D
Explanation:

Windbreaks are rows of trees and shrubs planted perpendicular to the prevailing wind direction. This helps to reduce wind erosion by slowing down the wind and preventing it from carrying away soil particles. Windbreaks also provide habitat for wildlife and can improve air quality.

What is the practice of using crop rotation to maintain soil fertility and reduce the risk of pests and diseases called?

  1. Contour Farming

  2. Strip Cropping

  3. Crop Rotation

  4. Terracing


Correct Option: C
Explanation:

Crop rotation is the practice of growing different crops in the same area in a sequential order. This helps to maintain soil fertility by diversifying the crops grown and reducing the risk of pests and diseases. Crop rotation also helps to improve soil structure and reduce erosion.

Which method of soil conservation involves using contour lines to determine the best way to farm a sloping field?

  1. Contour Farming

  2. Strip Cropping

  3. Terracing

  4. Windbreaks


Correct Option: A
Explanation:

Contour farming is a method of soil conservation that involves using contour lines to determine the best way to farm a sloping field. Contour lines are lines that connect points of equal elevation on a map. By following contour lines, farmers can avoid farming up and down the slope, which can lead to erosion. Contour farming helps to reduce erosion by slowing down the flow of water and preventing it from carrying away soil particles.

What is the practice of using terraces to reduce erosion on steep slopes called?

  1. Contour Farming

  2. Strip Cropping

  3. Terracing

  4. Windbreaks


Correct Option: C
Explanation:

Terracing is the practice of using terraces to reduce erosion on steep slopes. Terraces are level areas that are built along the contours of a slope. They help to slow down the flow of water and prevent it from carrying away soil particles. Terraces also help to conserve water by creating level areas where water can be stored and used for irrigation.

Which method of soil conservation involves planting different crops in alternating strips to reduce erosion and improve soil fertility?

Correct Option: C
Explanation:

Cover cropping is the practice of planting cover crops to protect the soil from erosion and improve soil health. Cover crops are plants that are grown to cover the soil and protect it from erosion. They also help to improve soil health by adding organic matter and nutrients.
