Data Story
About Soil in Stephens County, Texas
Productive Alfisols of North Central Texas
Stephens County is characterized by Alfisols, a taxonomic order known for being naturally productive and nutrient-rich. The soil is slightly alkaline with a pH of 7.27, sitting just above the state average of 7.09. These soils are foundational to the region's diverse agricultural and ranching history.
The Versatility of Clay Loam
The dominant texture is clay loam, featuring 24.6% clay and 43.8% sand. This mix provides enough clay for nutrient retention while the sand ensures the soil doesn't become impossibly heavy. It is a robust, workable soil that supports both native grasses and cultivated crops.
Above Average Organic Matter
The soil contains 1.70% organic matter, placing it just above the Texas state average of 1.66%. Its water capacity of 0.136 in/in also beats the state benchmark, providing a steady moisture supply for plants. These factors combine to create a soil profile with high growing potential for local farmers.
Well Drained but Slow Moving
While classified as well-drained, the soil falls into Hydrologic Group C, which has a somewhat slow rate of water transmission. This means that while it handles normal rain well, heavy downpours may lead to temporary surface saturation. Careful land grading is recommended for new gardens or construction projects.
Diverse Options for Zone 8a
Zone 8a allows for a wide range of planting, from pecans and peaches to summer squash and okra. The clay loam provides a sturdy base for deep-rooted perennials that can withstand the Texas wind. Dig in and start your garden; your soil has the structure to support a bountiful harvest.
