Correct Answer: Crop rotation

Solution : The correct answer is (c) Crop rotation

Crop rotation is a sustainable farming practice that involves the systematic planting of different crops in the same area over a sequence of seasons or years. It helps to improve soil fertility, manage pests and diseases, and reduce the reliance on chemical inputs. By alternating crops, farmers can break the life cycles of pests and diseases that target specific plants, reducing the need for pesticides and promoting natural pest control. Additionally, different crops have different nutrient requirements, so crop rotation helps to balance soil nutrient levels, minimize nutrient depletion, and reduce the need for excessive chemical fertilizers. Crop rotation is an effective strategy for maintaining soil health,promoting biodiversity, and improving long-term agricultural sustainability. In contrast, options a) Overuse of chemical fertilizers, b) Monoculture farming, and d) Excessive pesticide use are practices that can have negative environmental and ecological impacts and are not considered sustainable in the long term.
