Hello, I'll try as best as I can to answer your question.

MSU Turfgrass Research did a research study on high potassium rates with golf courses. The link is below describing the results.

No noticeable differences were found with high potassium rates effecting other nutrients.

In my years of making lawn recommendations, a high potassium test would mean apply no potassium till further soil tests indicate need.

It would be very helpful to me if you have a current soil test to please share it with me so I can analyze what else could be going on such as too high or too low pH, low phosphorus level, calcium and magnesium.

I would be glad to visit with you as well in trying to figure out what is going on with your lawn. I can be reached at hudsonh@anr.msu.edu or (989) 670-8145 cell.
