Take out the monopotassium phosphate and you pretty much have my base mix for Warm season turf. County Fertilizer ordinance prevent me from using Phosphate. I am sure I use a different source of Minor elements but the final Blend has got to be close. Truth is I spend more on Minors than Primary elements.

In the Old Days 21-0-0 and Ferrous Sulfate was the weapon of choice by most spray companies because it was cheap and gave a Black Green hue to the Turf. The problem was Ferrous Sulfate is like sand blasting the inside of you spray equipment. I forget who posted they still use that blend.
