Answer: Most soils can be improved greatly by working in several inches of organic matter such as compost, rotted autumn leaves, or whatever other materials you can obtain locally at reasonable expense. Then use an organic mulch in a layer about three inches deep year round. This will break down slowly over time and continue adding organic matter to the soil. You could also plant cover crops such as buckwheat in summer and annual rye in the fall to help loosen the soil and add ample amounts of organic matter. In some cases, adding a small amount of coarse builders' sand (not the fine beach sand) or fine grit can be helpful, but keep in mind that a clay soil with sand added will dry out hard -- just like brick. Your local county extension should also be familiar with your local soil and may have some recommendations as to how to improve it. I hope this helps.
