About Soil in Red River County, Texas

The sweet spot of soil acidity

Red River County features a pH of 6.69, which is very close to the national median of 6.5. This near-neutral acidity is more balanced than the typical Texas average of 7.09, making it highly versatile for gardening.

A sturdy mix rich in clay

The soil is a heavy mix containing 31.6% clay, 39.7% sand, and 28.7% silt. This high clay content provides excellent nutrient retention but can make the ground heavy and harder to till when wet.

Exceptional resilience against drought
