What is the definition of organic foods grown in the US and who sets the
standards? - ✔✔(1) Produced without conventional pesticides, synthetic
fertilizers, sewage sludge, bioengineering, and ionizing radiation. (2) USDA
What methods may be used to fertilize soils for organic farming? - ✔✔-
Addition of compost, animal manures, or green manures.
- Cover crops for protection from wind and water erosion.
What is crop rotation? Why is it used in organic farming? - ✔✔Rotate crops
grown or planting bed over time to interrupt insect life cycles, suppress soil
borne plant diseases, prevent soil erosion, build organic matter, fix
nitrogen, and increase farm biodiversity.
How are pests and weeds dealt with in organic farming? - ✔✔Last resort
use approved pesticides such as microorganisms, insecticides derived from
plants or approved synthetic substances.May release predatory insects.
- Mulch to smother weeds.
