Pros & Cons of Organic Farming
Transcript of Pros & Cons of Organic Farming
Also, it's very expensive!
Single farmers can produce more crops with the use of industrialized methods The process of organic farming is more time consuming and requires more skills that some farmers do not have
Not only are they costly, but these organic products are spoiled easily due to lack of preservatives climate change Organic farms produce smaller crops and lower yields compared to industrialized ones. Organic farming has lower productivity often with vegetables and other crops which means, organic products are not always available. Organic farming unfortunately has the ability to enhance emissions of carbon dioxide which can affect climate changes Whereas, conventional farming is able to produce products faster and plentiful.
Also the products from these farms are always available Pros! Basic Rules for Organic Farming
- No use of chemical fertilizers or synthetic drugs
- No use of genetically modified organisms
- Prevention from soil loss and erosion
- Promotion of biodiversity – support a range of crops, not a single species
Nutrition: Foods that are grown organically tend to have a higher nutritional value than that grown by modern conventional methods. This is because organically grown foods can absorb more nutrients and minerals from soil. Chemical-free: Organic food is free of health harming chemicals such as pesticides, fungicides and herbicides. Taste: The tastiness of fruit and vegetables is related to its sugar content, which in turn is a function of the quality of nutrition that the plant itself has enjoyed. Storage: Organically grown foods are nourished naturally. This means that the structural and metabolic integrity of their cellular structure is better than more conventionally grown products. This allows them to be stored longer and they do not show the latter’s vulnerability to rapid mold and rotting. Grower Benefits Weeds: Weeds can heal and restore damaged soils. When farmers husband the life of the soil, as they do in organic agriculture, the improved conditions deter many weeds and favor their crops. The healthier crops are also capable of competing with the weeds that are present. Lower Input Costs: Organic farmers do not have to spend a lot of money on fertilizers, pesticides and such since they do not use them. Value: Since organic foods have the greater food value, people are willing to pay more for them. Organic Farming and Biodiversity - Positive - Organic farming promotes biodiversity
- Organic farmers support a range of crops, not just a single species
- Habitats with a variety of species are shown to adapt better to environmental changes
- Organic farms support ecosystems
- Studies have shown that some organic farms can have between 46-72% more semi-natural habitats
- They can also host up to 30% more species and up to 50% more individuals than non-organic farms
- Birds, predatory insects, soil dwelling organisms, spiders and field flora benefit most from organic farming
- Organic farming also causes improvements in pollination, reduction of soil erosion, and natural pest reduction in crops and soils
Main Steps Organic farmers Take to Increase Biodiversity - Forgo use of herbicides
- Forgo use of chemically-synthesized pesticides
- Less and purer organic fertilizer
- More diversified crop rotation
- Higher percentage of semi-natural areas
- More diversified farm structure
- Higher percentage of arable and ecological areas
Arable: (land) Used or suitable for growing crops.
Semi-natural: a community found in an area where human activity occurs, but is not the dominant factor affecting its ecology.
Low Productivity Organic products are much more expensive compared to industrialized products.
Almost 50-100% more expensive! Climate Change in Biodiversity Although organic farming has positive effects on species, it can differ between organisms In a journal by Janne Bengtsson, Johan Anstrom and Ann-Christin Weibull, they tested certain organisms to see how they responded in their environments. Birds, predatory insects and plants responded postively to organic farming... ...while insects and pests did not. The point of this test was to show that the use of pesticides is actually beneficial and is able to decrease the amount of pests, insects and predators. Such as:
*These conditions can affect yield crops negatively Climate changes can also;
Maximize soil evaporation
Increase temperature In my opinion, I found that the test proved that pesticides are useful because it defends the crops from species that are trying to feed off of them Affects There may be many advantages when it comes to organic farming however, the disadvantages should be taken into consideration before judging coventional/industrialized farms. THE END. Organic farming does indeed affect biodiversity in a certain way that should be recognized
