An example of co-culture of Azolla and duckweed: "Azolla filiculoides and L.minor" by Mygaia at English Wikipedia (T.M.McKenzie)
What is it?
Azolla filiculoides is a small fern that floats on water similar to duckweed. It is native to North, Central and South America. Given appropriate nutrient and other conditions, Azolla can grow rapidly. It is rich in protein and minerals and can be used as animal fodder or for human consumption. While Azolla is not itself a nitrogen-fixing organism, it lives in symbiosis with certain cyanobacteria (Anabaena azollae) that fix nitrogen.

Uses
- animal fodder: cows, chickens, fish, pigs, goats, etc.
- for human consumption: salad; powder
- source of nitrogen fertilizer (widely used as N-source in rice cultivation in China during last 1000y)
- for biogas and biodiesel
- wastewater treatment
- initial soil biomining for nutrients: phosphorus and potassium from soil, to be used in agriculture
