Nitrogen and Phosphorus Loading

Nitrogen and phosphorus loading refer to the addition of these nutrients into water bodies, often from sources like agricultural runoff, sewage, and fertilizers. When excessive amounts enter lakes, rivers, or coastal areas, they can cause overgrowth of algae and aquatic plants, leading to problems such as oxygen depletion and harm to fish and other aquatic life. This process, known as nutrient pollution, can degrade water quality, create dead zones, and disrupt ecosystems. Managing nitrogen and phosphorus loading involves reducing runoff and controlling nutrient inputs to protect aquatic health and maintain clean, balanced water resources.
