I have access to a Lesco store, and am looking for suggestions on products I might obtain for them that would help some of my trouble lawns. I am finding in particular area ph's around 7.7 to 7.9. These all have low P and K. I am finding some as low as 7 lb's per acre of P and base saturation levels of 1.4 of K. I don't know if I should look at Sulphate of Potash in large quantities now, or Amonium Sulphate. I know there is no quick fix, but want to bring things around. I was thinking of using some starter fertilizer on these lawns to see how that worked. Another question I have is, one one test it shows 245 lb's of K per Acre which is fine, but the base saturation is 1.4 which is quite low. Can someone explain how this is? Is it due to the high ph of 7.9? Most lawns are cool season mix, or straight Ky Blue. Thanks for your help fellas.
