How does agriculture cause water pollution?

When these sources exceed plant needs, or are applied just before it rains, nutrients can wash into aquatic ecosystems.
How does agriculture affect aquatic life?
Agriculture affects water quality through the release of nutrients (as a result of soil management and fertiliser application) and other chemicals (e.g. pesticides) into the water environment, through biological contamination (e.g. from microbiological organisms in manure), and via soil being eroded and washed off …
