It looks as though the same qualities that make it good for chelating also causes it to absorb and hold herbicides...
It reads a lot like char, in fact, only char simply adsorbs as opposed to actually absorbing as stated in the article...

I would imagine there are any number of things that herbicide might bind with in the soils, and this is just one more... this one evidently will never 'let go'... interesting...
Now that I know that clay's texture(platelets) has nothing to do with water infiltration, percolation, or drainage
,,, I wonder what does...
