All nitrates are soluble, so whatever amount is not taken up by plants in a field is washed away into groundwater and, eventually, into rivers, streams, ponds, and lakes. In these bodies of water, the nitrates become sources of food for algae and other plant life, resulting in the formation of algal blooms.
