Nitrogen is necessary for all life
We get it from the earth
LEGUMES (bean plants) fix it in the earth because
They work with bacteria that attach to their roots
How do they do it?
Scientists have now followed the molecule messengers that start above ground
SEE THE LIGHT (sort of)
Are changed by the light
Go down into the roots
WHERE their changed form
Acts as a SWITCH that TURNS ON
The storage of NITROGEN
Symbiotic nitrogen fixation, the largest natural source of bio-usable nitrogen for the biosphere, influences primary production and carbon sink in agricultural and natural ecosystems ( Ref:D. S. LeBauer, K. K. Treseder, Ecology 89, 371–379 (2008).
