Pin Oak Chlorosis

I hae a 30 yr old Pin Oak that suffers from chlorosis. Over the years I've fed the tree with iron by solid and liquid applications to the trunk. I am at a point where drilling holes in the trunk and injecting iron produces minimal results. I would like to know what ground application chemical (sulfur or iron, etc), how to feed and the amount of chemical to put down. Thank you
