conventional farming
Conventional Farming
  • 1940’s began farming with agri-chemicals
    • Fertilizer, pesticides, herbicides, fungicides and rodenticides
  • 1972 Congress ordered the EPA to test all pesticides for potential health hazards.
    • All agri-chemicals can remain until EPA proves dangerous
  • 1990’s pesticide companies focus on genetic engineering
  • Using agri-chemicals is the predominate way food is grown in U.S. so it is now called “conventional” farming
organic farming
Organic Farming
  • Based on :
    • Using natural, renewable fertilizer and pesticides
      • Compost, manure, Bt
    • Farming in a way that maintains and replenishes the life and nutrients in the soil.
      • The farmer feeds the living organisms in the soil.
      • Handful of organic soil – 5 billion microorganisms
  • Primary methods used:
    • Crop diversity
    • Crop rotation
    • Biological pest control
organic foods
Organic Foods
  • Plants grown without conventional pesticides or fertilizers
  • Produced without genetically engineered seeds
  • Animals are fed organic feed and raised without use of antibiotics
