About Soil in Tunica County, Mississippi
Balanced pH in Tunica County
Tunica County features a pH of 5.78, making it the least acidic soil in this set and much closer to the national median of 6.5. It comfortably exceeds the Mississippi state average of 5.30.
High Clay Nutrient Storage
The soil contains a balanced 35.7% silt and 28.2% clay, with 28.3% sand. This high clay content provides excellent structure and nutrient-holding capacity for large-scale agricultural operations.
Rich Organic Matter Content

Slow Drainage, High Fertility
A clay content of 28.2% often slows drainage, meaning the soil remains damp for longer periods after a storm. This retention is a boon for long-term fertility but can delay planting during wet Mississippi springs.
Fertile Delta Planting
Situated in zone 8a, Tunica's rich 2.07% organic matter makes it some of the most fertile ground in the state. It is a premier location for growing hearty staples like corn, wheat, and sunflowers.
