There are very, very few plants (if any?) which can utilise atmospheric
nitrogen directly.
Isn't that basically what nitrogen fixation (as in legumes and some
other plants) is about?
Thats what I was thinking, but then they utilise mycorhizae (sp?) to do
it (in most cases AFAIK) so its indirect?
But in the context of the current discussion - legumes can wade in and
use the nitrogen whereas most other plants have to wait and hope it
becomes available. Like using fruit pickers as opposed to hoping the
fruit may fall off eventually.
