    I've only used it for balancing the ph level in the soil.

    Lime allows you to correct the PH of the soil. It normally takes some time for this to happen, which is why most suggest applying lime in the fall. The correct soil PH allows your fertilizer to work most effectively. Correct PH also is needed for proper lawn growth.

    As rtom45 pointed out, a neutral pH will increase efficiency of fertilizers by increasing the microbial activity in the soil. Lime will increase (sulfer will lower) the soil pH, but how effectively it will do so can only be determined by a soil test which will show the cation exchange capability (CAC) of the soil and will show you how much lime is needed. Keep in mind that more than 50lbs per 1000 is like taking to much vitamen C, a waste. Lime can be applied almost any time of year, we do it in the winter as we have no other work.

    One other thing about lime. It not only RAISES the pH of a soil, but it provides the soil with calcium. I have recieved soil test results before where no lime was required. However the calcium level was low. One way to raise calcium levels, without raising pH is by using epson salts. Calcium by the way provides cell walls with strength. Otherwise, if you are too deficient, your plants will be weak... tomatos get rotten, and certain other things happen.

    I've used lime several times to control moss growth on one of my clients lawns. About 25 pds. per 1,000 ft/sq kills out the moss and hasn't adversly affected the Ph. Don't ask me how it works, but it does!
  7. DO A SOIL TEST!!!!

    Lime mainly used to raise ph, but also to increase ca in soil if base saturation low.
    calacitic lime, or dolimitic lime depends on base saturation of ca and mg. Often gypsum used when ph ok, but ca is low. Only way to know, is to take a soil test.

    DO SOIL TESTING!!!!!!!!!!

    Lime can also eliminate moles, moles dont like bitter roots :)
