Abstract

Four different mesocosm scale constructed wetlands - monoculture (Carexstipata), self-designed (passive) community, mixed planted monoculturepassive community and a non-vegetated control were compared to assess the effects of plant community composition on the removal of inorganic nutrients from agricultural runoff (synthetic tile water). The mixed and self-designed systems consistently produced effl uent NO3-N concentrations signifi cantly below 10 mg/L, and had higher rates of evapotranspiration. Results indicate the type and composition of the plant community can impact the performance of constructed wetlands. Therefore, self-design of the plant community through the existing seed bank may increase the effectiveness of wetlands in treating agricultural runoff.
