What is a good ratio of potassium to nitrogen for cool season grass? I read mixed opinions . Most lawn care companies use products like 12-0-3 or 24-0-5 or 30-0-5. How much better would the turf look with something like 25-0-20? Assuming the lawn does not have a defeciency to begin with. I talked to a guy that manages a baseball field, and he said he is using 15lbs per k, per year, of potassium. I also read that if there is no defeciency then it makes no noticable difference to use more.

I will most likely to some tests myself at some point. I only have access to potassium chloride and k-mag. No potassium sulfate where I get my fert.
