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.
