What is nutrient loading?

Nutrient loading refers to the introduction of excessive nutrients, particularly nitrogen and phosphorus, into ecosystems, primarily through agricultural runoff, wastewater discharge, and industrial processes. This influx can lead to problems such as algal blooms, which deplete oxygen in water bodies and harm aquatic life. The resulting eutrophication can disrupt ecosystems, degrade water quality, and negatively impact fisheries and recreational activities. Managing nutrient loading is essential for maintaining ecological balance and protecting water resources.
