Hello all, my name is Mike. I'm from Greer, SC. I have turf type tal fescue in my lawn. Iv been in my house for almost 4 years and this January is the first soil test iv ever done. I had my local extension at Clemson do it. My PH is good. My P & K are in the high zone. My questions are.... how will my "high" P and K levels effect my lawn this year? I'v assume I won't be using a starter fert this fall when I overseed but rather a 34-0-0 like the test recommends. Iv already put the required amount of 34-0-0 for the spring. Would you all recommend putting any Milo out at all being it has some P in it? Can I expect my lawn to bring the P and K down over the next year? I plan on doing another soil test next January. Here is my soil test and a picture of my lawn I took about a week ago! Thanks for the help! I look forward to being an active member here.

Welcome to TLF. Your yard looks really nice.

High P and K are not a significant issue to your lawn. It is an envioriontal issue since it could Leach and get to the groundwater/rivers. The impact of your 12ksqft is nothing compared to acres of farm land.

Thanks for the compliment. So I shouldn't worry about the higher levels of P&K effecting the growth of my grass?

Your lawn looks great indeed. Congratulations!

About the high P & K, not only you shouldn't worry, you should feel happy about it. The ranges on soil tests generally tell you:
Low - must add nutrients, grass is struggling;
Medium - adding nutrients is likely to improve the grass;
Sufficient - adding nutrients is likely to result in just minor improvement, not worth it;
High - you might or might not see minor improvements by adding nutrients;
Excessive - adding nutrients is unlikely to help. For some nutrients, it may be harmful.

P & K are safe for your grass. and your test looks quite good overall.

Agree that your "high" values are not a problem.
Clemson used to use Mehlich L extraction, if they still do and you want to compare to recommended sufficiency ranges, you can find the Mehlich I (M1) ranges in this thread https://thelawnforum.com/viewtopic.php?f=22&t=1088
Clemson reports nutrient values in lbs, so you will need to divide pounds by two to convert to parts per million (ppm) to compare apples to apples on the M1 chart.
