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?
