About Soil in Scott County, Arkansas
Deeply acidic soils near the border
Scott County's soil shows an average pH of 5.42, which is significantly more acidic than the national median of 6.5. This pH level is also slightly below the Arkansas state average of 5.56. While specific taxonomic data is limited, the acidic profile suggests a landscape that requires careful nutrient management.
A balanced mix of sand and silt
The soil composition is nearly even, with 41.5% sand and 42.8% silt. This blend, combined with a 15.6% clay content, creates a medium-textured soil that is generally easy to cultivate. The balance of particles helps maintain a structure that supports both root growth and airflow.
Building fertility from a low base
Organic matter content is 1.61%, which is lower than the national 2.0% average and well below the state average of 4.15%. The available water capacity is 0.135 in/in, indicating a slightly lower ability to store water compared to the state average. Regular additions of mulch and compost are essential for long-term productivity.
Managing slow water movement in group D
The county's soils fall into hydrologic group D, which means they have very slow infiltration rates when thoroughly wet. This often results in high runoff and can lead to soggy conditions in low-lying areas. Farmers and gardeners should plan for drainage solutions to keep roots healthy during wet spells.
Abundant sunshine in hardiness zone 8a
In hardiness zone 8a, Scott County gardeners can enjoy a long season for growing tomatoes, corn, and squash. A soil score of 24.6 suggests there is plenty of room for improvement through soil amendments and smart drainage. Start small, test your soil, and watch your Arkansas garden flourish.
