Data Story
About Soil in Wilbarger County, Texas
Alkaline Alfisols of the Red River Valley
Wilbarger County is dominated by Alfisols, which are typically fertile soils often found under forests or grasslands. The average pH of 7.30 is more alkaline than the national median of 6.5 and slightly higher than the Texas average. These clay loam soils provide a robust, if somewhat basic, environment for agriculture.
The Texture of Clay Loam
The soil composition is 48.8% sand, 26.4% silt, and 20.9% clay, creating a classic clay loam texture. This mix offers a good balance between the drainage of sand and the nutrient retention of clay. Farmers find these soils manageable, though they require careful timing to avoid compaction when wet.
Thirsty Soils with Low Organic Content
Organic matter in Wilbarger is 1.03%, significantly lower than the Texas average of 1.66%. Despite low organic levels, the available water capacity matches the Wichita neighbor at 0.139 in/in, surpassing the state benchmark. This capacity is vital for sustaining crops in a region prone to dry spells.
Well-Drained Ground with Hydrologic Group C
The land is classified as well-drained, which is excellent for preventing root rot in sensitive plants. It belongs to Hydrologic Group C, indicating a somewhat slow infiltration rate when the soil is thoroughly wet. This combination makes it suitable for both grazing and cultivated crops.
Resilient Gardening in Zone 8a
In Zone 8a, your garden will thrive with plants like okra, peppers, and native wildflowers that handle alkaline conditions. Because the soil score is 25.3, just below the state average, adding compost can help improve the low organic matter. Your well-drained soil is a great asset for avoiding drainage issues in the backyard.
