OVERUSE OF FERTILIZERS AND ITS EFFECT ON AQUATIC ECOSYSTEMS Author name: Bismi Nazar Abstract The overuse of chemical fertilizers in modern agriculture has significantly contributed to the deterioration of aquatic ecosystems. Excess nutrients, particularly nitrogen and phosphorus, from agricultural runoff cause eutrophication, resulting in algal blooms, oxygen depletion, and loss of biodiversity in aquatic environments. This article examines the causes and effects of fertilizer overuse on aquatic ecosystems, explores potential mitigation strategies, and emphasizes the importance of sustainable agricultural practices to preserve water resources and biodiversity. Key Terms Fertilizers, Eutrophication, Algal blooms, Hypoxia, Dead zones. Content The increasing demand for agricultural productivity has led to the widespread use of chemical fertilizers, ensuring higher crop yields to feed a growing population. While fertilizers play a crucial role in modern farming, their overuse ...
