    How soon after the lime applications was the soil test done? I've seen that before. I would say that either the lawn has been excessively limed, or an app was done within a month of the soil test.

    As to how do you proceed? I wouldn;t do anything. Every time it (acid)rains the pH will go down. The high mag/ca content might gum up the works, tie some nutrients up, but shouldn't be anything major.

    On a magnesium or sodium driven ph of 7.7, calicitic lime could bring the ph down. On most ph over 8.4,( or is it 8.7?) lime will bring the ph down. Ph isnt a good indicator of whether or not you need lime, even tho it seems most people look at ph only to determine if they need lime.

    I am Not saying on this particular soil that lime is needed.

    So that is why it is important to know what is driving the pH. Thanks. I did not know that. :)

    Just thought of something else:

    Do you trust the lab that did the test? I've seen some wierd results come back. Friend of mine was a bio-chem major in college. He would tell me stories of what they did in the lab. Making hookas out of the flasks, getting laid, sleeping, etc. Not alot of science, but he had fun. (he currently makes $200+ a year working for a pahrmaceutical company!!)
