About Soil in Coahoma County, Mississippi
Delta Soil Near Neutrality
Coahoma County boasts an average pH of 6.07, making it one of the least acidic counties in Mississippi. This measurement is significantly closer to the national median of 6.5 than the state average of 5.30.
Heavy Clay and Delta Silt
The soil contains a substantial 31.2% clay and 43.9% silt, creating a dense, nutrient-rich environment. While this 25.0% sand content is lower than some areas, the clay provides the structural 'heaviness' the Delta is known for.
High Score Despite Low Organic Matter
While organic matter is slightly lower than the state average at 1.50%, the county earns a high soil score of 43.4. The clay-rich profile compensates by holding onto essential minerals very effectively.
Slow Drainage and Rich Retention
With an available water capacity of 0.165 in/in, this soil holds a steady supply of moisture. The high clay content means water moves slowly, which is great for moisture-loving crops but can lead to muddy conditions after heavy rains.
Delta Staples in Zone 8a
This zone 8a environment is world-famous for cotton and soybeans. For your home garden, choose okra or roses that can thrive in these heavier, more neutral Delta soils.
