dc.description.abstract The potential of using halophytic wetland plants for the removal Na+ and Cl- from recirculated greenhouse nutrient solution was assessed. Eight species were screened for their Na+ and Cl- removal capacity and it was determined that Schoenoplectus tabernaemontani and Typha latifolia were the best candidates. A second experiment examined the effect of harvesting and harvesting frequency on plants and their capacity to uptake Na+ and Cl-. Juncus torreyi and T. latifolia responded positively to harvesting and their Na+ and Cl- uptake and biomass production were increased when harvested once or twice throughout the growing season, but harvesting had no effect on S. tabernaemontani. The effect of solution NaCl concentration was investigated and both S. tabernaemontani and T. latifolia, accumulated more Na+ and Cl- at higher concentrations. Overall, the plants removed Na+ and Cl-, but the rates were too low to make it an effective Na+ and Cl- management option for the treatment of recirculated greenhouse nutrient solution. en_US
