    The response of Sparganium emersum to different sediment nutrient levels was studied in three mesocosm experiments. The experimental treatments were produced by fertilisation of the rooting with differing doses of either NPK mineral fertiliser or digested sludge from solid pig slurry waste. Growth inhibition by high nutrient levels was not observed in any treatment, which confirms the tolerance of S. emersum to high nutrient loads. The sediment nutrient concentration was best reflected in shoot dry mass. Nutrient contents in plant tissues were similar for most nutrient concentrations in the rooting media. Nutrient standing stocks in plants corresponded to the nutrient supply, and reached highest values in the richest treatments with organic fertiliser. The capability of S. emersum to use nutrients from high sediment concentrations and in organically polluted environments recommends this species for use in water quality management including tertiary wastewater treatment.
