Get your soil tested, either by a lab or you can buy a test kit at
most garden centers. Once you know what the PH is and what it should
be for the type of grass, you can determine the amount needed. The
bags of lime usually have info as to how much is needed to raise the
PH a specific amount.


And be clear about whether you are talking about real lime (CaO) or
limestone (CaCO3) which is sold as "lawn lime". The latter is ground up
seashells and does not dissolver quickly at all.


Almost all lime products for home lawn use are going to be slow dissolving.
This is what you want because it raises PH slowly and lasts longer. Any
product you get which is going to change PH rapidly is also going to be a
very hazardous product to work with meaning you'll need to wear a respirator
and eye protection. Pelletized, slow dissolving products are much better
suited for the home lawn application and can be easily applied with a garden
fertilizer spreader.

All lawn products have the calcium carbonate equivalent(CCE) marked on the
bag. All you have to do is divide the pounds of calcium carbonate called
for in the soil test by the CCE. For instance, lets say the soil test
indicates he needs 25 lbs of calcium carbonate per 1,000 sq ft. The product
he buys is Dolomite Lime, and is 45% CCE. All he has to do is divide 25 /
..45 to get 55 lbs of Dolomite Lime per 1,000 sq ft.
