Nitrogen and phosphorus removal from swine lagoon liquid by growing Lemna minor 8627, a promising duckweed
identified in previous studies, was investigated under in vitro and field conditions. The rates of nitrogen and phosphorus
uptake by the duckweed growing in the in vitro system were as high as 3.36 g m2 day1 and 0.20 g m2 day1, respectively.
The highest nitrogen and phosphorus removal rates in the field duckweed system were 2.11 g m2 day1 and 0.59 g m2 day1,
respectively. The highest observed duckweed growth rate was close to 29 g m2 day1 in both conditions.
