Question 5: What is the purpose of a buffer zone in an organic operation?
- A chemically treated perimeter surrounding the organic field
- An area separating organic fields from potential contamination sources (Correct answer)
- A zone restricted to mechanical pest control only
- A designated pesticide storage area
Correct answer: An area separating organic fields from potential contamination sources
Buffer zones protect organic fields from pesticide drift or contamination from adjacent non-organic operations.
