Nitrogen fixing trees!
Discussion
Red bud is a legume?
So actually it looks like I'm wrong, I thought it was a nitrogen fixer because it is a legume!
But supposedly it's not a fixer, but it is a legume!
I never thought it was a symbiotic relationship with bacteria. I assumed they absorbed nitrogen through the air and saved it in nodules.
Nitrogen in air has a triple or quadruple covalent bond or something in the air as gaseous N2. It’s inaccessible that way. The bacteria nodule things are capable though
The nodules are the bacterial colony. The bacteria inhale nitrogen from the air and combine it with the carbon skeletons from the sugars the plant produces to build amino acids to use in protein production.
