OBJECTIVES
The purpose was to study the response of the plant at several concentrations of ammonium and try to conclude on the maximum it can supports.
MATERIALS
The materials used to set up all this mini test:
- 7 blue plastics pots ; pliers to keep a plastic film above plants to prevent evaporation ;
- Precision balance;
- 1L volumetric flask for KNOP solution preparation ;
- Distilled water bottle ;
- Mixer with magnet to homogenize KNOP solution;
- 50 mL graduated tube to pour the right volume in each pot.

RESULTS
In general, the plants grew up well in the range of NH4+-N concentrations less than 200 mg/L.
CONCLUSION
The results demonstrated green roofs could treat domestic wastewater. More studies need to be done about this project to finally conclude on how to treat wastewater for a huge city.
