Abstract
Eutrophication is commonly understood as the excessive enrichment of nitrogen and phosphorus in aquatic systems, leading to algal blooms, oxygen depletion, habitat degradation, and water-quality deterioration. This article argues that eutrophication should not be treated merely as an end-point water-body problem, but as the aquatic manifestation of terrestrial metabolic rupture. Nitrogen and phosphorus are not pollutants by nature; they become pollution pressure when displaced from proper soil-plant-microbe-agricultural pathways and accumulated in water beyond ecological accommodation capacity. The article reconstructs the causal framework of eutrophication by redefining soil richness as the dynamic capacity to retain, slowly release, transform, and cycle nutrients. It further identifies microorganisms as the operating layer of soil fertility, mediating nutrient transformation, rhizosphere interaction, organic-matter decomposition, and aggregate formation. Long-term dependence on fast-acting chemical fertilizers may weaken plant-microbe mutualism and increase external-input dependence, while intensive livestock farming and monocropping generate spatial mismatch through localized metabolic overload and ecological impoverishment. The article concludes that eutrophication governance should move beyond nutrient removal and end-point remediation toward nutrient re-accommodation and pathway reorganization. Restoring soil organic matter, microbial networks, crop-livestock nutrient closure, and land-water transition zones is essential for returning nitrogen and phosphorus to agroecological cycles.
