About Soil in Saline County, Arkansas
Highly acidic Ultisols in Saline County
Saline County has an average pH of 5.15, making it the most acidic soil in this group and far below the national median of 6.5. These Ultisols are heavily weathered and typically low in natural bases like calcium. The dominant texture is a versatile loam that serves as the foundation for the local ecosystem.
A balanced loam with high silt
The soil is 45.5% silt and 40.2% sand, creating a loam that balances drainage with moisture retention. Only 14.3% of the soil is clay, which helps prevent the ground from becoming too sticky or heavy when wet. This mix is generally considered the 'gold standard' for workability in gardening.
Low organic matter requires active care
Organic matter is quite low at 1.38%, falling significantly short of the state average of 4.15%. Despite this, the available water capacity is 0.149 in/in, which is right on par with the state benchmark. This indicates that while the soil can hold moisture, it lacks the carbon-rich nutrients necessary for peak plant health.
Well-drained soil with steady infiltration
Classified as well-drained and part of hydrologic group B, these soils handle water efficiently. They allow for moderate infiltration, which protects plants from drowning during Arkansas's heavy spring rains. This drainage class also makes the county's land favorable for various construction projects.
Mastering the soil in zone 8a
Saline County's 8a hardiness zone is perfect for heat-loving vegetables, provided you amend the acidic soil. The low soil score of 19.9 highlights the need for lime and organic fertilizers to unlock the land's potential. With a little effort, your loam soil can become a powerhouse for your backyard garden.
