Nutrient Remediation using Two Plant Species in a Floating Treatment Wetland System
Garcia, L.M., Majsztrik, J.C., Bell, N.L., White, S.A. (Clemson University)
Excess nutrients are often present in production runoff from nurseries and greenhouses because fertilizers are used to grow plants. In 2015, we conducted trials with floating treatment wetlands (FTWs) to determine how much nutrients soft rush (Juncus effusus) and pickerelweed (Pontederia cordata) could absorb. When harvested after 20 weeks, with pond nutrient concentrations averaging 10 ppm N and 3 ppm P, a 1-acre are of planted FTWs would remove 88 lbs. of N and 15 lbs. of P if planted with soft rush or 1,320 lbs. of N and 255 lbs. of P if planted with pickerelweed.
