In what way does sustainable agriculture contribute to nutrient cycling?

Sustainable agriculture plays a crucial role in nutrient cycling primarily by enhancing soil health and nutrient retention. This approach emphasizes the importance of maintaining healthy soils, which are rich in organic matter, beneficial microorganisms, and diverse plant life. Healthy soils are better at retaining nutrients and water, making them more resilient and productive over time.

Practices associated with sustainable agriculture, such as crop rotation, cover cropping, and reduced tillage, contribute to improved soil structure and fertility. This leads to increased organic matter, which enhances the soil's capacity to store nutrients. Additionally, these practices promote the cycling of nutrients naturally, as plants and soil organisms work together to utilize available resources efficiently.

In contrast, options that suggest reliance on imported synthetic fertilizers or focus solely on monoculture practices do not support nutrient cycling in a sustainable manner. Dependence on synthetic fertilizers can lead to soil degradation and nutrient leaching, while monoculture reduces biodiversity and the natural processes that contribute to nutrient cycling.
