Someone once told me that the process involved when plant roots get nutrients
from substrate binding sites is called adsorption (with a "d"). As I remember,
the root trades an ion (or proton?) that it has for a nutirient ion like NH4++.
Do plants get chelated ions the same way? Trade something for the the Fe++ ion
in the chelator, for example?

Do you want to know how I did it?
