What is the definition of organic foods grown in the US and who sets the standards?
Ans>> (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?
Ans>> - 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?
Ans>> 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.
