What practice can help prevent eutrophication in water bodies?

Proper manure management plays a crucial role in preventing eutrophication in water bodies. Eutrophication occurs when excess nutrients, primarily nitrogen and phosphorus, enter aquatic systems, leading to overgrowth of algae, which can deplete oxygen levels and harm aquatic life. Effective manure management practices ensure that nutrients are applied at appropriate rates based on crop needs, minimizing runoff and leaching into nearby water sources.

By carefully handling manure, farmers can utilize its nutrient content efficiently while reducing the chances of excess nutrients washing into streams, rivers, and lakes during rain events or snowmelt. This not only protects water quality but also promotes healthier agricultural practices, enhancing soil structure and fertility without contributing to environmental degradation.

In contrast, over-fertilization, increased pesticide use, and reduced crop rotation can contribute to nutrient runoff, pesticide contamination, and soil health issues, all of which can exacerbate the risk of eutrophication. Thus, maintaining a focus on proper manure management is essential for sustainable agriculture and water conservation efforts.
