Plant crops under this tree, and watch your crop yields increase dramatically. The tree has the potential to aid farmers throughout Africa, South America, and much of south and Southeast Asia.
The issue here is nitrogen. It’s a very important component of fertilizer, and is currently provided through man made manufactured fertilizer. It can get really expensive, especially in cash strapped continents like Africa. The tree’s name is Faidherbia albida. It’s one of several trees that can capture nitrogen from the air through its roots and incorporate it into its leaves.
The kicker is that it grows in the dry season and drops its leaves in the rainy season, when crops start growing. The leaves drop with the nitrogen in them, and fertilize the crops below. That is, if they’re planted below.
Three- to four-fold increases in corn yields were reported, as well as yields for millet and cotton.
Why wasn’t this reported before? Other potentials for this tree are that it makes mining for fertilizer less necessary, once you have a natural source that sucks it out of the air and puts it in its leaves. That clears up a lot of pollution and industrial activity that is invested in producing potash, and things of the like.
