    I just got a soil test back and this is a first time I've ever had too add lime, 15lb per k. (Question) How long does it take for the ph to show some signs of change? thanks Tony :)

    Reaction from lime can take from four months to eight months. We usually ballpark around six months. The actual soil and plants will begin to benefit soon after the app but it might not be noticible to the eye.

    15# per K isn't much either, what was your pH based on teh soil test?

    i got a test back that was also 5.8 and i need 50#/K. 15#/k is not a lot. What lime are you using?

    I just received a soil test from the lab and it had a pH of 6.1 and recommended lime @ 46# per K.

    Is it safe to spread lime anytime of the year?

    Amount of lime needed to change soil p.h. varies depending on soil type. Ex. If you have a heavy clay soil it will resist change a lot more than sandy loam soil.

  7. what type of lime?
    dolomitic or calicitic?
    depends on base saturation of ca and mag!

    you can lime any time of the year. I talked to a guy from lesco today and said that he limed in mid summer and it reacted with soil quickly enough that he notice the bermuda greening up a bit. I'm not saying that it's ok any time of the year because he said that. Most of the time, i think, southern LCOs do it in the winter b/c there's nothing much else to do.
    Does the ph drop at a constant rate? can you plan to apply X anount/yr and the ph stay at 6.5? thanks
