North AL red clay needs lime and compost every year. Black Belt soils are naturally alkaline — don't add lime without testing first. South AL sand needs nitrogen and organic matter. Auburn Extension soil tests run $7.
Know your soil
North Alabama has red clay Piedmont soils — acidic, dense, needs organic matter. The Black Belt gets its name from its dark, calcium-rich, alkaline prairie soils — among the most naturally fertile in the South but sticky and hard to work when wet. South Alabama has sandy soils that drain fast and need regular amendment.
