What is the primary goal of organic farming?

  1. To maximize crop yield

  2. To reduce the use of synthetic pesticides and fertilizers

  3. To enhance soil fertility

  4. To promote biodiversity


Correct Option: B
Explanation:

Organic farming aims to minimize the reliance on synthetic chemicals and promote natural processes to maintain soil health and ecosystem balance.

Which of the following is a key principle of organic farming?

  1. Crop rotation

  2. Use of synthetic fertilizers

  3. Application of chemical pesticides

  4. Genetically modified crops


Correct Option: A
Explanation:

Crop rotation is a fundamental practice in organic farming, as it helps maintain soil fertility, control pests and diseases, and promote biodiversity.

How does organic farming contribute to soil health?

  1. By increasing the use of synthetic fertilizers

  2. By promoting the use of natural fertilizers and compost

  3. By reducing soil erosion

  4. By eliminating the use of cover crops


Correct Option: B
Explanation:

Organic farming practices, such as the application of natural fertilizers and compost, help improve soil structure, increase organic matter content, and enhance soil biodiversity, leading to improved soil health.

What is the role of biodiversity in organic farming systems?

  1. It increases the risk of pest outbreaks

  2. It reduces the need for synthetic pesticides

  3. It decreases the soil's ability to retain water

  4. It promotes the growth of weeds


Correct Option: B
Explanation:

Biodiversity in organic farming systems promotes ecological balance, enhances natural pest control mechanisms, and reduces the reliance on synthetic pesticides.

Which of the following is a common pest management strategy in organic farming?

  1. Use of broad-spectrum insecticides

  2. Biological control

  3. Application of chemical herbicides

  4. Genetically modified crops


Correct Option: B
Explanation:

Biological control, which involves the use of natural enemies to manage pests, is a key strategy in organic farming to minimize the reliance on synthetic pesticides.

How does organic farming contribute to the conservation of natural ecosystems?

  1. By increasing the use of synthetic fertilizers

  2. By reducing habitat fragmentation

  3. By promoting the use of genetically modified crops

  4. By increasing soil erosion


Correct Option: B
Explanation:

Organic farming practices, such as the maintenance of natural habitats and the promotion of biodiversity, contribute to the conservation of natural ecosystems and the preservation of wildlife.

What is the primary certification standard for organic farming?

  1. ISO 14001

  2. ISO 9001

  3. Organic Trade Association (OTA) standards

  4. Good Agricultural Practices (GAP) standards


Correct Option: C
Explanation:

The Organic Trade Association (OTA) standards are widely recognized as the primary certification standard for organic farming, ensuring compliance with organic production methods and practices.

Which of the following is a challenge faced by organic farmers?

  1. Lower crop yields compared to conventional farming

  2. Higher production costs

  3. Lack of access to synthetic pesticides and fertilizers

  4. All of the above


Correct Option: D
Explanation:

Organic farmers often face challenges such as lower crop yields, higher production costs, and limited access to synthetic pesticides and fertilizers, which can make organic farming more demanding.

How can consumers support organic farming?

  1. By purchasing organic products

  2. By advocating for policies that support organic farming

  3. By educating themselves about organic farming practices

  4. All of the above


Correct Option: D
Explanation:

Consumers can support organic farming by purchasing organic products, advocating for policies that promote organic agriculture, and educating themselves about organic farming practices, thereby creating demand and raising awareness.

What is the long-term impact of organic farming on soil health?

  1. It leads to soil degradation and loss of fertility

  2. It improves soil structure and increases organic matter content

  3. It has no significant impact on soil health

  4. It increases the risk of soil erosion


Correct Option: B
Explanation:

Organic farming practices, such as crop rotation, cover cropping, and the use of natural fertilizers, contribute to the long-term improvement of soil structure, increase organic matter content, and enhance soil biodiversity.

Which of the following is a key benefit of organic farming for consumers?

  1. Reduced exposure to synthetic pesticides and fertilizers

  2. Improved nutritional value of food

  3. Lower food prices

  4. All of the above


Correct Option: A
Explanation:

Organic farming practices minimize the use of synthetic chemicals, resulting in reduced exposure to pesticides and fertilizers for consumers, potentially leading to health benefits.

How does organic farming contribute to climate change mitigation?

  1. By increasing greenhouse gas emissions

  2. By reducing the use of fossil fuels

  3. By promoting the use of genetically modified crops

  4. By increasing deforestation


Correct Option: B
Explanation:

Organic farming practices, such as reduced reliance on synthetic fertilizers and the use of cover crops, contribute to climate change mitigation by reducing the use of fossil fuels and sequestering carbon in the soil.

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

  1. To control weeds

  2. To improve soil fertility

  3. To reduce soil erosion

  4. All of the above


Correct Option: D
Explanation:

Cover crops play a multifaceted role in organic farming systems, providing benefits such as weed control, soil fertility improvement, and reduction of soil erosion.

How does organic farming promote biodiversity in agricultural ecosystems?

  1. By reducing the use of synthetic pesticides and fertilizers

  2. By maintaining natural habitats and hedgerows

  3. By promoting crop diversity

  4. All of the above


Correct Option: D
Explanation:

Organic farming practices, such as reduced use of synthetic chemicals, maintenance of natural habitats, and promotion of crop diversity, contribute to the enhancement of biodiversity in agricultural ecosystems.

What is the primary challenge faced by organic farmers in pest management?

  1. Lack of access to synthetic pesticides

  2. Difficulty in controlling pests without synthetic chemicals

  3. Increased risk of pest outbreaks

  4. All of the above


Correct Option: D
Explanation:

Organic farmers face challenges in pest management due to the limited availability of synthetic pesticides, the need for alternative pest control strategies, and the potential for increased pest outbreaks in the absence of conventional chemical treatments.
