D.4. Eutrophication
[Classification of eutrophication]
- Algal bloom is a visible ecological phenomenon where the surface of a water body becomes covered with dense layers of green algae, often in response to the introduction of natural or artificial nutrients.
- This bloom is a direct result of eutrophication, driven by an excess of nitrates and phosphates from sources such as fertilizers and sewage. These nutrients act as a catalyst for rapid growth of algae and blue-green bacteria, leading to a sudden population surge that blankets the water’s surface.
- To help manage this, nitrogen testing is employed to determine the precise amount of fertilizer needed by crops, helping to minimize nitrogen runoff into nearby aquatic systems.
