Cheng et al. (2010)

Initially-equal fresh weights (0.2g) of the aquatic fern grown for 16 days at high (34/26°C) day/night air temperature (T) regimes within controlled-environment chambers in pots filled with 5 kg gray sandy soil collected from the plow layer of a typical rice field, but now saturated with water that extended to about 15 cm above the surface of the soil in which rice and some aquatic weeds were also growing

Cheng et al. (2010)

Initially-equal fresh weights (0.2g) of the aquatic fern grown for 28 days within controlled-environment chambers in pots filled with 5 kg gray sandy soil collected from the plow layer of a typical rice field containing low levels of phosphorus (P), but now saturated with water that extended to about 15 cm above the surface of the soil in which rice and some aquatic weeds were also growing
