Data Story
About Soil in Medina County, Texas
Alkaline Soils in the Medina Valley
Medina County features an average pH of 7.33, placing it notably higher than the national median of 6.5. While taxonomic data is currently unavailable for this specific region, the alkaline nature suggests a presence of calcium-rich materials. This basic environment influences how plants absorb essential nutrients from the ground.
A Balanced Mix of Sand and Clay
The soil composition is a diverse blend of 42.5% sand, 28.6% clay, and 26.8% silt. This moderate mix creates a surface that is easier to work than pure clay but retains more moisture than pure sand. It offers a stable foundation for varied agricultural activities across the county's landscape.
High Organic Matter Boosts Growth
At 2.22%, the organic matter content exceeds both the state average of 1.66% and the national average of 2.0%. The available water capacity stands at 0.132 in/in, which is nearly identical to the Texas state average. These factors combine to provide a fertile environment for local producers.
Managing High Runoff Potential
The county falls into Hydrologic Group D, indicating soils with very low infiltration rates when thoroughly wetted. While specific drainage class data is missing, this group typically presents a high risk for surface runoff during heavy Texas rainstorms. Builders and farmers must plan for significant water movement across the terrain.
Thriving in Hardiness Zone 9a
The warm climate of Zone 9a allows for long growing seasons and mild winters. Mediterranean herbs, citrus, and heat-tolerant vegetables like okra flourish in this alkaline, organic-rich soil. Local gardeners should embrace the long summers and start planting early to beat the peak heat.
