Conventional vs. Organic Agriculture

Exploring the differences between conventional and organic agriculture

2

Organic vs. Conventional Agriculture

  • Organic: Uses natural fertilizers to promote plant growth. Natural fertilizers are derived from organic matter such as compost, manure, and cover crops.
  • Conventional: Relies on synthetic fertilizers to enhance plant growth. These fertilizers are made from chemicals and minerals.

3

Multiple Choice

What is the main difference between organic and conventional agriculture?

1

Organic agriculture uses natural fertilizers derived from organic matter, while conventional agriculture relies on synthetic fertilizers made from chemicals and minerals.

2

Organic agriculture relies on synthetic fertilizers made from chemicals and minerals, while conventional agriculture uses natural fertilizers derived from organic matter.

3

Both organic and conventional agriculture use natural fertilizers derived from organic matter.

4

Both organic and conventional agriculture rely on synthetic fertilizers made from chemicals and minerals.

4

Organic vs Conventional

Did you know that organic agriculture uses natural fertilizers derived from organic matter, while conventional agriculture relies on synthetic fertilizers made from chemicals and minerals? This fundamental difference impacts the overall sustainability and environmental impact of each farming method.

5

Implications of Conventional Agriculture

  • Water: Synthetic fertilizers can pollute waterways, affecting drinking water and aquatic ecosystems.

  • Soil: Conventional practices can lead to soil erosion, compaction, and decreased health and productivity.

  • Biodiversity: Synthetic insecticides and GMO seeds limit biodiversity, increasing the risk of crop loss.

  • Energy Inputs and Emissions: Conventional agriculture has higher energy inputs and greenhouse gas emissions compared to organic agriculture.

6

Multiple Select

What are some implications or drawbacks of conventional agriculture?

1

Decreased health and productivity of soil

2

Greater crop yields

3

Higher energy inputs and greenhouse gas emissions

4

Limited biodiversity

5
  • Attracts beneficial birds, insects, and pollinators

7

Benefits of Conventional Agriculture

  • Reduced Labor: Advanced machinery and technology in conventional farming reduce the need for manual labor, making it more efficient.

  • High Yields: Conventional farming often achieves high crop yields due to the use of synthetic fertilizers, pesticides, and advanced farming machinery. This helps meet the demands of a growing global population.

  • Market Availability: Conventional farming is the predominant method used in many regions, ensuring a steady supply of conventional produce in the market.

8

Multiple Select

What are some merits or benefits of conventional agriculture?

1

Reduced labor

2

Synthetic fertilizers pollute waterways

3

High crop yields due to farming machinery

4

Low energy inputs

5

Produces a steady supply of produce

9

Implications of Organic Agricultural

  • Higher Costs: Organic food can be more expensive because it often requires more labor and care.

  • More Labor: Organic farming can require more work because it often relies on manual labor instead of machines.

  • Pest and Disease Management: Organic farming avoids synthetic pesticides, so it can be more challenging to control pests and diseases, which can harm crops.

11

Benefits of Organic Agriculture

  • Enhanced soil structure and water retention

  • Reduced leaching of nutrients into waterways

  • Higher yields during drought years

  • Lower energy inputs and emissions

  • Improved public health by avoiding synthetic pesticides

  • Increased soil biodiversity and protection from pests and diseases

  • Attracts beneficial birds, insects, and pollinators

  • Greater genetic diversity of seeds for crop resilience

12

What are some benefits of organic agriculture?

1

Increased soil biodiversity and protection from pests and diseases

2

Health risks for farmers

3

Higher yields during drought years

4

Lower energy inputs and emissions

5

Limited biodiversity

13

Organic vs. Conventional Agriculture

  • Organic farms contribute to carbon sequestration in soils through practices like minimum tillage and cover cropping.

  • Organic farming reduces health implications for farmworkers and consumers by avoiding synthetic pesticides and limiting nutrient runoff.

  • Organic produce is generally more expensive due to limited production, high demand, and small-scale operations.

  • Smaller organic farms often implement more favorable organic growing practices than larger farms.

14

Why is Organic Produce Expensive?

  • Limited Production: Organic farming is a smaller-scale operation, resulting in limited supply.

  • High Demand: The increasing popularity of organic produce drives up the demand.

  • Small-Scale Operations: Organic farms often have higher production costs due to their size.

15

Multiple Select

Why is organic produce more expensive than conventional?

1

Organic farming is a smaller-scale operation, resulting in limited supply.

2

Synthetic chemicals create health risks for farmers.

3

4
  • Organic farms often have higher production costs due to their size.

5
  • Advanced machinery and technology make it more efficient.

16

Which organic foods are worth your dollar?

Organic foods tend to cost more than their conventional counterparts. So which foods are worth the added expense? It has been found that even after you wash certain fruits and vegetables, they still contain much higher levels of pesticide residue than others. Researchers at the Environmental Working Group (EWG) have analyzed more than 100,000 U.S. government pesticide test results and developed the “Dirty Dozen” fruits and vegetables, as well at the “Consistently Clean”.
