A. caroliniana was introduced to southeast Asia as a bio-fertilizer and weed suppressor in rice fields. For centuries this species has been exploited for its ability to fix nitrogen through its symbiotic bacteria that exists in cavities within the leaves. Additionally, weeds are suppressed because very little usable light is transmitted through the canopy that A. caroliniana creates. This quality translates into more nutrients for the plants being cultivated above surface. Control of this species is easy because it floats on the top of the water; there are no roots attached to anything but the plant itself. The ease of removal makes this a great species to use for such an application. When the time comes to remove the A. caroliniana, the unwanted plants are collected by simply skimming them from the surface.
If there were self replicating machines that could coat earth's surface with light reflecting material, this could help reduce earth's temperature. Better still would be self replicating machines that somehow sequestered gigatons of atmospheric carbon dioxide. About 50 million years ago there was a freshwater arctic fern known as Azolla. It grew on the surface, but when it died it sank into the cold water, where it was covered and preserved. Over hundreds of thousands of years this fern pulled billions of tons of CO2 out of the atmosphere, causing earth to cool, and ultimately resulting in a long series of ice ages. One could view Azolla as nanotechnology--a self replicating machine. But its growth rate would probably be too slow to be of much service to us.

A biofertilizer is any variety of biologically-produced fertilizer.
Azolla primaeva was created in 1890.
Azolla filiculoides was created in 1783.

A biofertilizer is a biological fertilizer. Meaning, it is not composed of chemicals. Some biofertilizers include horse and chicken manure.
Azolla is a type of fern that has been around since the time of the Dinosaurs. It is a bio fertilizer that may be used in paddy fields and similar cultivation to avoid harsh chemical fertilizers that destroy the soil.
nitrogen fixing bacteria , phosphate
Anabaena azollae is the cyanobacterium that lives in the dorsal lobe of the Azolla leaves
azolla is a good substitute for commercial fertilizers because it is cheap and rich in nitrogen
