<human>:  What type of soil is best for growing potatoes?
<bot>: The best type of soil for growing potatoes is well-draining loam soil with a slightly acidic pH between 5.0 and 6.5. It should be rich in organic matter and have good drainage and aeration. Sandy loam or silt loam soil is also a good choice for growing potatoes, as it offers good aeration and drainage while also providing the potatoes with enough nutrients.
