How to use lime; how much to use

Question

I haven’t been able to do a reliable, understandable soil test of soil under my cedar tree. I want grass to grow there. I’ve got lime (calcium carbonate type). Can I dig some in without knowing the exact quality to use? I’ve removed this year’s catkins and needles from the ground around the tree. I’d like to get on with improving that area of lawn. Thanks.

The best thing you can put under a tree is mulch out to the canopy dripline.

Here is lime info:
