Data Story
About Soil in Cochran County, Texas
Alkaline Extremely Gravelly Loam
Cochran County features an average pH of 7.78, making it one of the more alkaline areas compared to the 6.5 national median. The dominant texture is an extremely gravelly loam, which is unique among its neighboring counties. This stony, alkaline base defines the local growing conditions.
A Gritty, Sandy Foundation
The soil is comprised of 61.4% sand, 20.0% silt, and 18.6% clay. This high sand and gravel content creates a very porous environment where roots can easily travel. However, such a high sand percentage means the soil can dry out quickly without proper management.
Moderate Water and Low Organic Matter
The soil holds 0.127 in/in of water, which is just below the Texas average of 0.133 in/in. Organic matter is also lean at 1.29%, trailing the state average of 1.66%. Improving this through cover cropping or composting is essential for long-term soil health and fertility.
Moderately Well Drained Group B
Unlike many neighbors, Cochran County features 'Moderately well drained' soil and belongs to hydrologic group B. This means it has a moderate infiltration rate, allowing water to soak in more effectively than the tighter soils of the region. This classification is an advantage for preventing runoff and erosion.
Sturdy Growth in Zone 7b
In USDA Hardiness Zone 7b, Cochran County is well-suited for drought-tolerant crops and native xeriscaping. Plants that prefer better drainage and can handle alkaline gravel will thrive here. Consider starting a garden with lavender, sage, or other hardy perennials that love this specific soil.
