The pickerel weed, canna and bullrush are growing well - filling out the 2" thick polypropylene platform, and providing a two-tiered platform for removing Nitrogen and Phosphorous. Firstly, the dense root system allows for microbe activity and digestion to occur just below the surface. Secondly, the plants ingest Nitrogen and Phosphorous as part of their required nutrients, sequestering both in the biomass.
These floating platforms of wetland plants function on a Nutrient In - Nutrient Out basis as described below - perfect for a TMDL nutrient removal program.
