Possibly the biggest news in agriculture since hybrid corn. Some crops (like soybeans) can 'fix nitrogen' in their roots, actually by using symbiotic microbes to produce it. Corn, rice, wheat have relied upon the soil to produce it through rotting organic matter.<p>Commercial farmers rarely plow organic matter (manure) into topsoil any more. They instead spray anhydrous ammonia, produced from propane(?) using tractors and sprayers. They do this usually once. The crop needs it continuously, so they apply 10X-100X what's needed to ensure a supply when needed. Which can 'burn' the crop and change the biosphere.<p>This microbe will recycle atmospheric nitrogen instead of converting (and releasing CO2) from propane. Its greener by 100X. And the crop improvements should convince any farmer to convert to this technique.
