Correct Option (b)
Permaculture farming is a sustainable agricultural design system that models natural ecosystems, emphasizing long-term ecological balance. It contrasts with conventional chemical farming, which often relies on synthetic inputs for short-term yield optimization.
- Statement 1 is correct: Permaculture discourages monocultural practices, promoting biodiversity through polyculture and integrated systems. Conventional chemical farming, conversely, is characterized by widespread monoculture due to its focus on mechanization and specialized input application.
- Statement 2 is correct: Excessive use of chemical fertilizers and improper irrigation in conventional chemical farming can lead to soil salinity and degradation. Permaculture farming, by relying on organic inputs, mulching, and natural water management, significantly reduces the risk of such soil issues.
- Statement 3 is incorrect: The statement "Conventional chemical farming is easily possible in such regions" is vague and lacks specific context regarding "such regions," rendering it unsuitable for comparison or factual assessment.
- Statement 4 is correct: Mulching is a fundamental practice in permaculture, crucial for moisture retention, weed suppression, soil temperature regulation, and enhancing soil health. In conventional chemical farming, where synthetic herbicides and irrigation are common, mulching is not a primary or essential practice.
Incorrect Options
- Option (a) is incorrect because it includes statement 3, which is vague and incorrect, and omits statement 2, which correctly highlights a key difference.
- Option (c) is incorrect because while statement 4 is correct, it overlooks other significant differences presented in statements 1 and 2.
- Option (d) is incorrect because it includes the vague and incorrect statement 3, and excludes statement 1, which accurately describes a core distinction.
