    How long does it take before the lime actually starts to make a change? After a good rain or weeks or months?

    Days to years depend on the type of lime applied.Dolomitic,Ground,Hydrate Agricultural,Burnt(quick) Liquid and pelletized limestone all respond differently.

    Be very carefull with fast acting lime as they are caustic.

    Don't try to change soil pH too quickly.

    The soil test came back stating to use Dolomitic to correct @54#'s/K. Knowing this how long?

    Application methods will determine how long it takes to treat your soil. Most soil test companies will recommend enough lime to fix a 6 inch layer of soil. If you are incorporating the lime 6 inches deep then the time to neutralize your soil would be a lot less than if you broadcast the entire amount to the soil surface. Lime applied to the soil surface has shown up in leaf sampes of the plant in as little as three days after application and a good rain event. Correcting the Soil ph probably take 3 months with incorporation, and 3 years if just broadcast on top. On establish turf, you can apply the entire amount 54 lbs without any negaitve results. On new seeding, split the application n half and make two application about 6 months apart.

    Typically a pelletized lime will take about 4-6 months before there is a significant change in pH. As garydale said, " Don't try to change the soil pH too quickly."

    So...being nearly APRIL & I need to slit seed, which I will have to do early fall, will the lime have enough effect on the soil so the seed will grow? Being everything else being equal? The current level is 5.3:confused:

    Since you will be broadcasting the lime on top of the soil, the best you can hope to correct is going to be about 3 to 4 inches of the soil this year. Apply half the lime now, which would be the correct amount for you to use to fix the top 3 inches. After seeding and later this fall, you can apply the the remaining amount of lime. Your pH isnt all that much off, most plants grow best at a ph of 6.0 to 6.5. 5.3 is 10 times more acidic than 6.3 but grass will grow fine at that pH.
