Organic Farming?• To be considered “organic”: – must be produced without synthetic pesticides, fungicides or herbicides. – Can not be grown by use of genetic engineering – Bans use of sewage sludge as fertilizers – No irradiation of food to preserve it – No use of hormones and/or antibiotics in organic meat and diary products Strict farming methods = costly production
History of Organic Farming• Organic Farming was the original type of agriculture.• Forest gardening, a fully organic food production system which dates from prehistoric times.• The organic movement began in the mid- 1920s in central Europe.
Organic Farming MethodsIt is a combine scientific knowledge of ecology and modern technology with traditional farming practices based on naturally occurring biological processes. • Crop Diversity • Pest Control • Live Stock • Farm Size • Plant Nutrition – Soil Fertility
Advantages of Organic Farming:• conventional farmer’s can actually reduce production cost by over 25%.• eliminating the use of synthetic fertilizers and pesticides.• minimizing soil erosion by up to 50% and increasing crop yields up to five-fold within 5 years.• free from harmful chemicals, artificial flavors and preservatives.• Eating organic foods may in fact, reduce the risk of heart attacks, strokes and cancer.
Benefits of Organic Farming:• Yield• Energy• Greenhouse gas emissions and climate change• Water use• Localisation• Pesticides• Ecosystem impact• Nutritional benefits• Seed-saving• Job creation
Environmental benefits of Organic Farming:• SOIL- building practices such as crop rotations, inter- cropping, symbiotic associations, cover crops, organic fertilizers and minimum tillage are central to organic practices.• WATER- In many agriculture areas, pollution of groundwater courses with synthetic fertilizers and pesticides is a major problem.• AIR&CLIMATE- Organic agriculture reduces non-renewable energy use by decreasing agrochemical needs. And contributes to mitigating the greenhouse effect and global warming through its ability to sequester carbon in the soil.
