Commercial nurseries use large amounts of water and nutrients to produce container-grown plants. The large volume of runoff containing nitrogen (N) and phosphorus (P) that leaves nurseries can contaminate surface and groundwater. Subsurface flow-constructed wetlands have been shown to effectively treat agricultural, industrial, and residential wastewater and to be well-suited for growers with limited production space. We investigated the possibility of using commercially available aquatic garden plants in subsurface-constructed wetlands to remove nutrients in a laboratory scale, gravel-based system. Seven popular aquatic garden plants received N and P from Hoagland's nutrient solution every 2 days for 8 weeks. These rates (0.39 to 36.81 mg·L−1 of N and 0.07 to 6.77 mg·L−1 P, respectively) encompassed low to high rates of nutrients found at various points between the discharge and inflow points of other constructed wetland systems currently in use at commercial nurseries. Plant biomass, nutrient recovery, and tissue nutrient concentration and content were measured. Whole plant dry weight positively correlated with total N and P supplied. Louisiana Iris hybrid ‘Full Eclipse’, Canna × generalis Bailey (pro sp.) ‘Bengal Tiger’, Canna × generalis Bailey (pro sp.) ‘Yellow King Humbert’, Colocasia esculenta (L.) Schott ‘Illustris', Peltandra virginica (L.) Schott, and Pontederia cordata L. ‘Singapore Pink’ had the greatest N recovery rates. The P recovery rates were similar for the cannas, Colocasia esculenta ‘Illustris’, Louisiana Iris ‘Full Eclipse’, Pe. virginica, and Po. cordata ‘Singapore Pink’. The potential exists for creating a sustainable nursery and greenhouse production system that incorporates a subsurface-constructed wetland planted with marketable horticultural crops that provide remediation and revenue.

“…Many soluble inorganic nutrients (such as nitrate) are removed by macrophytes from the water column by direct uptake (Greenway, 2007 ). Therefore, many species that can efficiently accumulate biomass might increase the nitrate uptake (James et al, 2005 ; Weisner and Thiere, 2010 ) and accumulate nitrogen in their biomass (Barbieri et al, 1984 ; Nogueira and Esteves, 1993 ), which in turn reduces the nitrate availability in the waterbodies.…”

Associations between Macrophyte Life Forms and Environmental and Morphometric Factors in a Large Sub-tropical Floodplain

Macrophyte assemblages are composed of species with different life forms and various ecological functions. Our aim was to investigate the potential environmental determinants of changes in the biomass of individual life forms and of the composition of the macrophyte assemblage in terms of life forms diversity. We sampled 23 waterbodies at low and high water levels in the Middle Paraná River floodplain. Macrophyte biomass samples were collected and classified in terms of life forms. We performed a redundancy analysis using the biomass of the various life forms to assess the importance of environmental variables to the composition of macrophyte life forms. Linear regressions were applied to investigate the environmental determinants of the biomasses of individual life forms. The degree of connectivity and the combination of depth, hydrology and nitrate were the main determinants of the composition in terms of life forms. The biomass of each individual life form was explained by different combinations of environmental variables, but the connectivity was the most important one. Our study shows that groups of species with similar life forms respond to environmental factors in particular ways, which might alter the biomass composition of life forms. Given that the ecosystem functioning depends on the functional characteristics of local communities, our findings about the relation between environmental changes and the community composition in terms of life forms (or functional composition) can be a helpful tool for predicting changes on ecosystem processes (such as nutrient cycling) against possible future scenarios.

“…Independent of the low concentration of available nitrogen and phosphorus in the water, the macrophytes stocked large quantities of these nutrients in their biomass. Barbieri et al (1984), in a study of N. indica and P. cordata in Lobo Reservoir, showed that these plants stocked six times more N and ten times more P in their biomass than was present in an equal area of surrounding water.…”

“…Investigations on the chemical composition of aquatic macrophytes are important, since besides furnishing data on the capacity for nutrient stocking in the biomass of these plants (Esteves, 1979(Esteves, , 1980Barbieri et al, 1984), they also permit the evaluation of nutrient availability for growth (Gerloff & Krombholz, 1966;Howard-Williams, 1985). In Lobo Reservoir this type of study assumes even greater importance since about 12% of it is covered by a dense aquatic macrophyte community which is fundamentally involved in the detritus chain (Camargo, 1984).…”

The concentration of nutrients in Nymphoides indica (L.) 0. Kuntze, Pontederia cordata L., Andropogon bicornis L. and Utricularia breviscapa Griseb was analyzed at monthly intervals from January 1980 through February 198 1. The macrophytes strongly influenced the organic nitrogen and phosphorus concentration of the water, mainly in those months of intense plant decomposition after a dry period. The monthly changes in chemical composition of the macrophytes and in water are discussed.
