You can find all ingredients for Floratine products here :
http://agr.wa.gov/PestFert/Fertilizers/ ... ?pname=105 This website has all manufacturers´ products.
I think some health food stores may be cheaper than Floratine. Soil microorganisms in a biologically active rootzone will naturally chelate the micronutrients. If you want to try something, buy the generic quantities of the Floratine products and apply them side by side and evaluate the difference.
