Data Story
About Soil in Gaines County, Texas
Sweet Soils of the High Plains
Gaines County has an average pH of 7.77, which is notably more alkaline than the national median of 6.5. While detailed taxonomic data is sparse, the high pH is a hallmark of this semi-arid region. This alkalinity requires specific plant choices that can tolerate lime-rich earth.
Predominantly Sandy and Rapidly Draining
The profile is 67.4% sand, the highest among its neighbors, with only 15.5% clay. This means water moves through the ground very quickly, often leaving the surface dry. Farmers here must manage irrigation carefully to prevent nutrient leaching.
Challenging Fertility in West Texas
Organic matter is low at 1.08%, well below the state average of 1.66%. The available water capacity is 0.123 in/in, which also trails the Texas average of 0.133 in/in. Frequent organic amendments are necessary to sustain intensive gardening.
Managed Runoff on the Plains
Classified in hydrologic group D, the soil exhibits high runoff potential once the sandy top layer is saturated. Though specific drainage classes are not recorded, this group suggests water does not penetrate deeply very fast. Careful site grading is essential for any new construction projects.
Hardy Grains and Cotton in Zone 8a
In Hardiness Zone 8a, growers find success with hardy grains and cotton that tolerate sandy conditions. The high sun exposure provides ample energy for growth if water is managed well. Your garden can thrive with native species adapted to these alkaline plains.
