Nope bit all my fert is zinc coated..and copper granuals, aim is to go liquid.
For my toolondo block I was very happy with the chelates trace pack...it saves the upfront cost, can mix with UAN...will use again up there for sure..will most likely use DAP coated zinc there instead of standard...or liquid...the heads should be bigger up there...anyways lacking rain so no biggie...
Black label zinc? Better be better than black label JW??
