Which of the following practices contributes to sustainable agriculture?

Crop rotation is a key practice that contributes to sustainable agriculture because it enhances soil health, increases biodiversity, and reduces dependence on chemical inputs. By alternating different crops in a specific sequence over time, farmers can improve soil fertility through diverse root structures and organic matter contributions. This practice also disrupts the life cycles of pests and diseases that typically thrive on a single crop, decreasing the need for chemical pesticides. Additionally, crop rotation can optimize nutrient utilization, allowing different crops to access various soil nutrients effectively, which leads to healthier and more productive ecosystems. Overall, this practice promotes resilience in agricultural systems, making them more sustainable in the long term.
