Answer: Potatoes thrive in well drained soils. They don't need a rich soil, but the biggest concern with fertility is the nitrogen in the soil. Too much nitrogen, especially in the form of fresh manures, can cause poor tuber formation. So if you are amendingyour soil with compost..., do so in the fall before planting. The pH should be between 6 and 6.5 which makes it easier for potato scab control. Other than that, as long as you add well rotted materials the fall before and till it in well, potatoes shouldgrow fine in most soils.
