I did a soil test of my backyard and am unsure how to proceed with the results. My calcium at ~546ppm is way over. No idea how to lower that or if I should even worry about it. Sulphur is high at ~15ppm. I had wanted to lower my pH slightly but with the high sulphur I'm not sure that's possible.
I was planning to start a twice-a-year topdressing with compost and sand to help level all my dips.
This is a Zoysia/Bermuda mix yard in what I think is clay soil. I'm told my neighborhood was basically built on top of limestone and they had to haul in all the topsoil, of which I don't have much, and another reason why I'm topdressing.
With their fertilizer recommendations and my topdressing, is the high Ca and S something I can do about and/or should even worry about?
