What is the primary purpose of crop rotation in organic farming?

  1. To control pests and diseases

  2. To improve soil fertility

  3. To increase crop yield

  4. To reduce the need for pesticides


Correct Option: A
Explanation:

Crop rotation helps break pest and disease cycles by disrupting their life cycles and reducing their populations.

How does crop rotation contribute to soil fertility in organic farming?

  1. By adding nitrogen to the soil

  2. By increasing soil organic matter

  3. By reducing soil erosion

  4. By improving soil structure


Correct Option: B
Explanation:

Crop rotation helps increase soil organic matter through the addition of diverse plant residues, which enhances soil fertility and improves soil health.

Which of the following is NOT a benefit of crop rotation in organic farming?

  1. Reduced reliance on synthetic fertilizers

  2. Improved soil biodiversity

  3. Increased susceptibility to pests and diseases

  4. Enhanced water infiltration and retention


Correct Option: C
Explanation:

Crop rotation actually helps reduce the susceptibility of crops to pests and diseases by breaking pest and disease cycles.

What is the concept of companion planting in organic farming?

  1. Planting different crops together to enhance their growth and resilience

  2. Planting crops in a specific sequence to control pests and diseases

  3. Planting crops in a way that maximizes sunlight exposure

  4. Planting crops in a way that minimizes water usage


Correct Option: A
Explanation:

Companion planting involves planting different crops together to benefit from their complementary growth habits, pest control properties, and nutrient cycling.

How does crop diversity contribute to the resilience of organic farming systems?

  1. It reduces the risk of crop failure

  2. It enhances the natural control of pests and diseases

  3. It improves the soil's ability to retain nutrients

  4. All of the above


Correct Option: D
Explanation:

Crop diversity provides multiple benefits, including reducing the risk of crop failure, enhancing the natural control of pests and diseases, and improving the soil's ability to retain nutrients.

Which of the following is NOT a common crop rotation sequence in organic farming?

  1. Legumes - Cereals - Root Crops

  2. Grasses - Legumes - Root Crops

  3. Cereals - Legumes - Grasses

  4. Root Crops - Legumes - Cereals


Correct Option: D
Explanation:

Root Crops - Legumes - Cereals is not a common crop rotation sequence in organic farming.

How does crop rotation help manage soil erosion in organic farming?

  1. By reducing the need for tillage

  2. By increasing the soil's organic matter content

  3. By improving soil structure

  4. All of the above


Correct Option: D
Explanation:

Crop rotation helps manage soil erosion by reducing the need for tillage, increasing soil organic matter content, and improving soil structure.

What is the role of cover crops in organic farming systems?

  1. To suppress weeds and reduce erosion

  2. To improve soil fertility and structure

  3. To attract beneficial insects and pollinators

  4. All of the above


Correct Option: D
Explanation:

Cover crops provide multiple benefits, including suppressing weeds and reducing erosion, improving soil fertility and structure, and attracting beneficial insects and pollinators.

Which of the following is NOT a benefit of crop diversity in organic farming?

  1. Reduced risk of crop failure

  2. Enhanced natural pest and disease control

  3. Increased soil erosion

  4. Improved soil fertility


Correct Option: C
Explanation:

Crop diversity does not lead to increased soil erosion; instead, it helps improve soil health and reduce erosion.

How does crop rotation contribute to the sustainability of organic farming systems?

  1. By maintaining soil fertility

  2. By reducing the need for synthetic inputs

  3. By enhancing biodiversity

  4. All of the above


Correct Option: D
Explanation:

Crop rotation contributes to the sustainability of organic farming systems by maintaining soil fertility, reducing the need for synthetic inputs, and enhancing biodiversity.

What is the primary goal of organic farming practices?

  1. To produce high yields

  2. To minimize environmental impact

  3. To maximize profits

  4. To reduce labor costs


Correct Option: B
Explanation:

Organic farming practices aim to minimize environmental impact by promoting sustainable agriculture and reducing the use of synthetic chemicals.

How does crop rotation help control pests and diseases in organic farming?

  1. By disrupting pest and disease cycles

  2. By reducing the use of pesticides and herbicides

  3. By increasing the diversity of beneficial insects

  4. All of the above


Correct Option: D
Explanation:

Crop rotation helps control pests and diseases by disrupting pest and disease cycles, reducing the use of pesticides and herbicides, and increasing the diversity of beneficial insects.

Which of the following is NOT a common practice in organic farming?

  1. Using synthetic fertilizers

  2. Crop rotation

  3. Composting

  4. Cover cropping


Correct Option: A
Explanation:

Using synthetic fertilizers is not a common practice in organic farming, as organic farming emphasizes the use of natural inputs and methods.

How does crop diversity contribute to the resilience of organic farming systems?

  1. By reducing the risk of crop failure

  2. By enhancing the natural control of pests and diseases

  3. By improving the soil's ability to retain nutrients

  4. All of the above


Correct Option: D
Explanation:

Crop diversity contributes to the resilience of organic farming systems by reducing the risk of crop failure, enhancing the natural control of pests and diseases, and improving the soil's ability to retain nutrients.

What is the role of beneficial insects in organic farming systems?

  1. To pollinate crops

  2. To control pests and diseases

  3. To improve soil fertility

  4. All of the above


Correct Option: D
Explanation:

Beneficial insects play multiple roles in organic farming systems, including pollinating crops, controlling pests and diseases, and improving soil fertility.
