The New Green Revolution:Hybrid System of Phytoremediation and Food Production in Eutrophicated Ponds/Lakes

Water issue adressed: Too dirty

In both kidney beans and maize systems, the combination of nitrifying bacteria and mycorrhizal fungi can eliminate the nitrogen concentration effectively, and the growth of maize and kidney beans was enhanced by the existence of nitrifying bacteria.
On-site pilot experiments indicated that maize and kidney beans in the local lake provided an energy-saving and cost-effective alternative instead of conventional energy-intensive systems for water purification.

This is how I came up with the idea for this project:

We originally researched water purification system that uses flowers. We tried to develop the system to contribute in solving the problems in the world. Then we invented a hybrid system of phytoremediation and food production.
