You will need to amend it with something to do so. Perlite, Vermiculite, (small amounts of) sand, coco coir, peat moss, dolomitic lime, and compost can be added each year, or biennially to keep the soil at its best.

One other thing to consider is earthworms. They are superior at loosening compacted soils.
