About Soil in Swisher County, Texas

Alkaline Mollisols Define the High Plains

Swisher County features Mollisols, a fertile soil order known for its dark, nutrient-rich surface. The soil maintains a loam texture with a pH of 7.84, which is significantly more alkaline than the national median of 6.5.

A Balanced Mix of Silt and Clay

The soil composition is remarkably balanced with 31.8% sand, 35.1% silt, and 31.5% clay. This loam texture provides excellent workability for farmers while retaining the structure necessary to support heavy machinery.

High Organic Matter Boosts Growth Potential

Organic matter sits at 2.07%, surpassing both the Texas average of 1.66% and the national average. Combined with an available water capacity of 0.154 in/in, these soils offer superior moisture storage for dryland farming.

Well Drained Soils Support Steady Infiltration

The land is classified as well drained and belongs to hydrologic group B. This combination allows for moderate infiltration rates, reducing the risk of surface runoff during heavy Panhandle rainstorms.

Thriving in the Zone 7a Climate

Located in hardiness zone 7a, this soil is ideal for winter wheat, cotton, and grain sorghum. Gardeners can find great success with peppers and tomatoes by managing the alkaline pH with organic amendments.
