About Soil in Cross County, Arkansas

Acidic silt loams define the region

Cross County features an average pH of 5.67, which is typical for Arkansas but below the national median of 6.5. This acidity level generally supports forest growth and specific agricultural crops like rice. Producers often apply lime to balance the soil for more sensitive garden plants.

Silt-rich profile for smooth workability

Silt dominates the soil at 58.3%, the highest fraction in the mix, followed by 21.8% clay and 19.9% sand. This high silt concentration provides a smooth, flour-like texture that is very easy to work for tillage. However, this composition can be prone to erosion if left uncovered by vegetation.

Exceptional water storage capacity

The available water capacity is a robust 0.191 in/in, significantly higher than the Arkansas average of 0.148 in/in. While organic matter is low at 1.47%, the soil’s ability to hold water makes it highly productive. This creates a resilient environment for crops during the hot summer months.

Managing water on the landscape

Specific drainage and hydrologic group data are currently limited for this county. Given the extremely high silt content, the soil likely holds moisture well but may suffer from surface crusting. Implementing cover crops can help maintain soil structure and improve water infiltration.

A long season in zone 8a

The county resides in USDA hardiness zone 8a, offering a generous window for growing warm-season crops. The water-retentive silty soil is ideal for tomatoes, peppers, and leafy greens. Gardeners should take advantage of the early spring and late fall to maximize their harvests.
