Which of the following is a common method of soil erosion control in agricultural areas?

  1. Contour plowing

  2. Strip cropping

  3. Terracing

  4. All of the above


Correct Option: D
Explanation:

Contour plowing, strip cropping, and terracing are all common methods of soil erosion control in agricultural areas.

What is the purpose of contour plowing?

  1. To create ridges and furrows that help slow down water runoff

  2. To create a level surface for planting

  3. To improve drainage

  4. To reduce soil compaction


Correct Option: A
Explanation:

Contour plowing is a method of plowing that follows the contours of the land, creating ridges and furrows that help slow down water runoff and reduce soil erosion.

Which of the following is a type of vegetative cover that can help control soil erosion?

  1. Grass

  2. Trees

  3. Shrubs

  4. All of the above


Correct Option: D
Explanation:

Grass, trees, and shrubs can all help control soil erosion by providing a protective cover that reduces the impact of raindrops and wind, and by holding the soil in place with their roots.

What is the purpose of terraces in soil erosion control?

  1. To create a level surface for planting

  2. To slow down water runoff

  3. To reduce soil compaction

  4. To improve drainage


Correct Option: B
Explanation:

Terraces are earthen embankments that are constructed across the slope of a hill or mountain to slow down water runoff and reduce soil erosion.

Which of the following is a type of structural measure that can be used to control soil erosion?

  1. Retaining walls

  2. Check dams

  3. Gabions

  4. All of the above


Correct Option: D
Explanation:

Retaining walls, check dams, and gabions are all types of structural measures that can be used to control soil erosion by physically preventing the movement of soil.

What is the purpose of crop rotation in soil erosion control?

  1. To improve soil fertility

  2. To control pests and diseases

  3. To reduce soil compaction

  4. To break up hardpans


Correct Option:
Explanation:

Crop rotation is a method of farming in which different crops are grown in the same area in a sequential order. This helps to improve soil fertility, control pests and diseases, reduce soil compaction, and break up hardpans, all of which can contribute to soil erosion.

Which of the following is a type of conservation tillage practice?

  1. No-till farming

  2. Strip-till farming

  3. Mulch-till farming

  4. All of the above


Correct Option: D
Explanation:

No-till farming, strip-till farming, and mulch-till farming are all types of conservation tillage practices that leave crop residues on the soil surface, which helps to protect the soil from erosion.

What is the purpose of windbreaks in soil erosion control?

  1. To reduce wind speed

  2. To trap snow

  3. To provide habitat for wildlife

  4. All of the above


Correct Option: D
Explanation:

Windbreaks are rows of trees or shrubs that are planted to reduce wind speed, trap snow, and provide habitat for wildlife. They can also help to control soil erosion by reducing the impact of wind on the soil.

Which of the following is a type of biological measure that can be used to control soil erosion?

  1. Planting cover crops

  2. Using compost

  3. Applying mulch

  4. All of the above


Correct Option: D
Explanation:

Planting cover crops, using compost, and applying mulch are all types of biological measures that can be used to control soil erosion by improving soil structure, increasing organic matter content, and reducing the impact of raindrops and wind on the soil.

What is the purpose of grassed waterways in soil erosion control?

  1. To provide a safe passage for water to flow

  2. To reduce soil compaction

  3. To improve drainage

  4. All of the above


Correct Option: D
Explanation:

Grassed waterways are channels that are covered with grass and are designed to provide a safe passage for water to flow, reduce soil compaction, and improve drainage. This helps to control soil erosion by preventing water from flowing over the land and carrying away soil.

Which of the following is a type of mechanical measure that can be used to control soil erosion?

  1. Contour plowing

  2. Strip cropping

  3. Terracing

  4. All of the above


Correct Option: D
Explanation:

Contour plowing, strip cropping, and terracing are all types of mechanical measures that can be used to control soil erosion by physically preventing the movement of soil.

What is the purpose of contour strip cropping in soil erosion control?

  1. To create a level surface for planting

  2. To slow down water runoff

  3. To reduce soil compaction

  4. To improve drainage


Correct Option: B
Explanation:

Contour strip cropping is a method of farming in which different crops are grown in strips that follow the contours of the land. This helps to slow down water runoff and reduce soil erosion.

Which of the following is a type of vegetative measure that can be used to control soil erosion?

  1. Planting trees

  2. Planting shrubs

  3. Planting grass

  4. All of the above


Correct Option: D
Explanation:

Planting trees, shrubs, and grass are all types of vegetative measures that can be used to control soil erosion by providing a protective cover that reduces the impact of raindrops and wind, and by holding the soil in place with their roots.

What is the purpose of terraces in soil erosion control?

  1. To create a level surface for planting

  2. To slow down water runoff

  3. To reduce soil compaction

  4. To improve drainage


Correct Option: B
Explanation:

Terraces are earthen embankments that are constructed across the slope of a hill or mountain to slow down water runoff and reduce soil erosion.

Which of the following is a type of structural measure that can be used to control soil erosion?

  1. Retaining walls

  2. Check dams

  3. Gabions

  4. All of the above


Correct Option: D
Explanation:

Retaining walls, check dams, and gabions are all types of structural measures that can be used to control soil erosion by physically preventing the movement of soil.
