What is the primary purpose of contour plowing?

  1. To reduce soil erosion

  2. To improve soil drainage

  3. To increase crop yield

  4. To control weeds

Show answer
Correct Option: A
Explanation:

Contour plowing is a farming technique that involves plowing along the contours of a slope, rather than up and down. This helps to slow down the flow of water and reduce soil erosion.

Which type of soil is best suited for contour plowing?

  1. Sandy soil

  2. Clay soil

  3. Loam soil

  4. Gravelly soil

Show answer
Correct Option: C
Explanation:

Loam soil is a mixture of sand, silt, and clay, and it is the best type of soil for contour plowing because it is less prone to erosion.

What is the ideal slope for contour plowing?

  1. Less than 2%

  2. 2-5%

  3. 5-10%

  4. More than 10%

Show answer
Correct Option: B
Explanation:

The ideal slope for contour plowing is between 2% and 5%. Slopes that are too steep or too flat are not suitable for contour plowing.

How does contour plowing help to reduce soil erosion?

  1. By slowing down the flow of water

  2. By increasing the infiltration of water

  3. By trapping sediment

  4. All of the above

Show answer
Correct Option: D
Explanation:

Contour plowing helps to reduce soil erosion by slowing down the flow of water, increasing the infiltration of water, and trapping sediment.

What are some of the benefits of contour plowing?

  1. Reduced soil erosion

  2. Improved soil moisture retention

  3. Increased crop yields

  4. All of the above

Show answer
Correct Option: D
Explanation:

Contour plowing has a number of benefits, including reduced soil erosion, improved soil moisture retention, and increased crop yields.

What are some of the challenges of contour plowing?

  1. It can be more time-consuming than traditional plowing methods

  2. It can be difficult to plow on steep slopes

  3. It can be difficult to maintain contour lines over time

  4. All of the above

Show answer
Correct Option: D
Explanation:

Contour plowing can be more time-consuming than traditional plowing methods, it can be difficult to plow on steep slopes, and it can be difficult to maintain contour lines over time.

What are some of the alternative methods to contour plowing for reducing soil erosion?

  1. Strip cropping

  2. Terracing

  3. No-till farming

  4. All of the above

Show answer
Correct Option: D
Explanation:

Strip cropping, terracing, and no-till farming are all alternative methods to contour plowing for reducing soil erosion.

Which of the following is NOT a benefit of contour plowing?

  1. Reduced soil erosion

  2. Improved soil moisture retention

  3. Increased crop yields

  4. Increased water runoff

Show answer
Correct Option: D
Explanation:

Contour plowing helps to reduce soil erosion and improve soil moisture retention, but it does not increase water runoff.

What is the most common type of contour plowing?

  1. Parallel contour plowing

  2. Oblique contour plowing

  3. Contour strip cropping

  4. Contour terracing

Show answer
Correct Option: A
Explanation:

Parallel contour plowing is the most common type of contour plowing. It involves plowing along the contours of a slope in parallel lines.

What is the difference between contour plowing and strip cropping?

  1. Contour plowing is done on slopes, while strip cropping is done on flat land

  2. Contour plowing is done with a plow, while strip cropping is done with a cultivator

  3. Contour plowing involves plowing along the contours of a slope, while strip cropping involves planting different crops in alternating strips

  4. Contour plowing is more effective at reducing soil erosion than strip cropping

Show answer
Correct Option: C
Explanation:

Contour plowing involves plowing along the contours of a slope, while strip cropping involves planting different crops in alternating strips.

What is the difference between contour plowing and terracing?

  1. Contour plowing is done on slopes, while terracing is done on flat land

  2. Contour plowing is done with a plow, while terracing is done with a bulldozer

  3. Contour plowing involves plowing along the contours of a slope, while terracing involves building level terraces on a slope

  4. Contour plowing is more effective at reducing soil erosion than terracing

Show answer
Correct Option: C
Explanation:

Contour plowing involves plowing along the contours of a slope, while terracing involves building level terraces on a slope.

What is the difference between contour plowing and no-till farming?

  1. Contour plowing is done with a plow, while no-till farming is done without a plow

  2. Contour plowing is done on slopes, while no-till farming can be done on any type of land

  3. Contour plowing involves plowing along the contours of a slope, while no-till farming involves leaving crop residues on the field

  4. Contour plowing is more effective at reducing soil erosion than no-till farming

Show answer
Correct Option: A
Explanation:

Contour plowing is done with a plow, while no-till farming is done without a plow.

Which of the following is NOT a type of contour plowing?

  1. Parallel contour plowing

  2. Oblique contour plowing

  3. Contour strip cropping

  4. Contour terracing

Show answer
Correct Option: D
Explanation:

Contour terracing is not a type of contour plowing. It is a different method of soil erosion control that involves building level terraces on a slope.

Which of the following is NOT a benefit of contour plowing?

  1. Reduced soil erosion

  2. Improved soil moisture retention

  3. Increased crop yields

  4. Increased water runoff

Show answer
Correct Option: D
Explanation:

Contour plowing helps to reduce soil erosion and improve soil moisture retention, but it does not increase water runoff.
