I have managed to locate a source of trace elements and would like to present the ingredients to the list for opinions. Ingredients are % when soluble: B 0.875 Cu 1.70 Fe 3.35 Mw 1.70 Mo 0.023 Zn 0.60 Obviously the Iron level is reasonably low and the mixture could do with a little extra added. Would I also need to add extra EDTA if I add more Iron? How do the ingredients appear to everyone? Andrew
