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
