At my previous course, I used Harness. I went from my first year at 15 gal/A to the second year at 30 gal/A, and then my third year at 45 gal/A. I put in on my tees, fwys, and greens every year. Loved the product, saw a nice color response, and it held for the duration of what rate you go. Got some really nice pics that I can send to you if you like. You get a pretty good burst of growth the very first time you use it, due to it helping release some other fertilizer that is in the soil, but after that it was fine. My email is
bryan_vice@hotmail.com if you have any more questions about regarding Harness.
