If your soil is typical Gumbo Mud you will need to add soil amendments to help loosen it up, it definitely is not soil for planting potatoes. We would bust the soil up any way possible and add truck loads of mulch and sand. Sometimes we would add peat moss and that helped keep the soil loose.
It is too late to do this now but a large amount manure tilled in to the soil makes it real nice for next year.
