bout 9-12". Tree has had a flower bed built up around it over the last 20 years with mulch and now beds are being removed.
I would only do this an inch or two at a time, so that the roots can have time to acclimate to the air. As long as this is allowed to happen over time, I don't think that there will be an issue. The roots of pines can handle exposure to the air usually, but since this has been under mulch, I would recommend air exposure a little more slowly.
What can I add to my garden to balance out a lot of pine needles in my soil?
I would first have your soil tested; this is really the only way to make a determination on what your soil may need for amendments or what your soil ph is.
Your County Extension Office can help you with a soil test.
These links will help you.

Image of tree need help identifying.
I'm thinking now these may be Bald Cypress. Overall shape of the trees looks to me like some images of Bald Cypress that are on line. Needles look same to me also. Or it's another Cypress very close in appearance.
From the photos it appears to be African Fern Pine (Afrocarpus gracilior).
But I would be surprised to see mature trees in Zipcode 45432 if that's Dayton Ohio, because of the limited cold tolerance for this species.
Photos added regarding tree ID question submitted earlier
Am attaching a close up of needles on this tree. The answer was helpful. If it's the African fern pine the 2 large ones are very close together. I walked around the area where they are and there are a couple more small ones that do not look as good as these 2. Not sure if you are local but these are in Beavercreek OH. There is a newer subdivision bordering I675. There is a deep retention area in middle of 2 plants perhaps 2 acres. Runoff collects here from the plats, a creek and I675 via culverts. Ducks, cranes etc. inhabit area also. The reason for explanation is that it is perhaps more protected here and a bit warmer than I'd they were out in open country. I loved them and had not seen any like them before and wondered where to get one for my yard! Looking inside T trunk and how branches come out from trunk it looks very much like a long needle pine I have. Thanks
Not African fern pine. You're right it looks like bald cypress. I'm not sure, And no I'm not local but a California arborist.

I need a low but wide pine tree to provide a natural barrier. I initially was thinking a Japanese Red Pine but I dont think they would grow well here in Philadelphia and its in a somewhat shaded area. Any suggestions ?
Pines, are generally not shade tolerant, but some other pine family conifers are. Here are a couple of articles that might help you with possibilities. Check the cold tolerance of any selection you are considering, Philadelphia is in USDA plant hardiness zones 7A and 7B. You can do that by entering a search phrase like this: - plum yew plant hardiness zone -

Hello and thanks again for your help. My pine trees are starting to turn yellow and brown. I live in Maryland and it’s been an especially soggy summer if that means anything. I have 13 and they are all starting to do it. Should I add fertilizer?
The most common cause of brown pine needles occurs in the fall and is normal. Pines shed older needles similarly to other trees’ fall foliage drop. The needle drop may be impressive in a large healthy tree. These needles make great mulch.
