Aquatic plants accumulate large quantities of nitrogen and phosphorus in their tissues. They will therefore improve soil if applied as soil additives. The concept of biofertilizers, the growing of a minor crop that provides nutrients to a major crop, though relatively new to aquatic science, is already becoming popular. Azolla sp., a free floating fern which fixes nitrogen. Perhaps this is the plant in question.
