Leave Selma going N towards Plantersville all sandy, no prairie.

Leave Selma on 22 toward Orrville there's some Prairie on S side of road once you cross Cahaba River. Mostly sandy on both sides of 22 until you get closer to Safford. Not much prairie going east on 14 toward Prattville. Mostly sandy dirt. Hwy 80 going east will get you to some once you pass old Dan River Mills. Hwy 80 going west will take you to some in Marion Junction. Stays pretty gummy from there to Demopolis.

Everywhere in Dallas county is NOT prairie (black belt) soils.

Millers Ferry to Demopolis, to Safford is close to solid prairie.
