The two main sources of nutrient inputs that contribute to eutrophication are:

a. Agricultural runoff and sewage discharge

These two sources are the primary contributors to eutrophication.

1. Agricultural runoff: This occurs when water, from rain, irrigation, or other sources, flows over the land and into bodies of water, carrying with it nutrients from fertilizers used in farming. These nutrients, primarily nitrogen and phosphorus, can cause an overgrowth of algae in the water, leading to eutrophication.

2. Sewage discharge: This refers to the release of wastewater from homes, industries, and other sources into bodies of water. This wastewater often contains high levels of nutrients, which can also contribute to the overgrowth of algae and eutrophication.
