Description
Fertilizer runoff is a major cause of harmful algal blooms. This runoff can be high in nitrogen content which is one of the major metabolites of plants. Nitrogen is usable by plants after it undergoes nitrogen-fixation by microbes. As an effort to reduce the effects of algal blooms, cover crops are a major area of research. Cover crops can be planted with desired crops and along waterways in an attempt to reduce the concentration of the causative agents of these blooms. Two aquatic plants found in coastal Georgia were used for this study. Compared to Vallisneria spiralis, we hypothesized that Eichhornia crassipes would be the most efficient at taking up excess nitrogen from fertilizer due to its extensive root system. Aquatic plants were favored over terrestrial plants for this study in terms of saving media and space. Additionally, it is thought that these aquatic plants may be a more direct method of rapid nitrogen uptake.
