Which is not true about organic agriculture?

Correct option is D

The correct answer is (D) Weed control and fertilization are not the challenges faced by organic crop producers

Explanation:
• This statement is false because weed control and nutrient management (fertilization) are actually the biggest challenges in organic farming.
• Without synthetic herbicides, organic farmers must rely on mechanical cultivation, mulching, and manual labor, which are often less efficient.
• Without synthetic fertilizers, ensuring adequate nitrogen and phosphorus availability through manures and composts requires careful planning and significant volume.

Information Booster:
• OFPA 1990: The US federal law that established national standards for organic products.
• Biodiversity: A core pillar of organic farming, emphasizing natural ecological balance.
• Certification: To sell products as 'organic', farmers must undergo a rigorous 3-year transition period and annual inspections.

Additional Knowledge:
• Option A is true in the context of global standards often derived from the US and IFOAM frameworks.
• Option B and C are defining characteristics of the organic philosophy and regulatory environment.
