About Soil in Ashley County, Arkansas
Acidic Ultisols of Ashley County
Ashley County features Ultisols, which are highly weathered soils common in the humid Southeast. The average pH of 5.47 is more acidic than the state average of 5.56 and significantly lower than the national median of 6.5. This natural acidity reflects a landscape that has seen heavy rainfall and leaching over centuries.
Sandy Loams with Silt Dominance
A fine sandy loam texture dominates the area, comprised of 54.3% silt and 28.1% sand. This mixture provides a more porous structure than neighboring counties, allowing for easier root penetration and tillage. The 17.5% clay content is sufficient to hold onto essential fertilizers while preventing the soil from becoming too heavy.
Deep Reservoirs for Summer Growth
The county boasts an available water capacity of 0.182 in/in, far surpassing the Arkansas state average of 0.148. While the organic matter is low at 1.59%, the soil's ability to hold water provides a critical safety net for vegetation. This high water capacity makes it an excellent candidate for intensive gardening if organic amendments are added.
Optimized Drainage for Versatile Use
Classified as well drained and part of hydrologic group B, these soils offer moderate infiltration rates even when wet. This makes the land highly versatile for both agricultural production and residential construction projects. You can expect fewer issues with standing water here compared to much of the Arkansas Delta.
Lush Potential in Southern Arkansas
