Data Story

About Soil in Wilson County, Texas

Neutral Ground in South Central Texas

Wilson County hits the state average exactly with a pH of 7.09. This neutral profile is slightly higher than the national median of 6.5 but is very versatile for most crops. While its taxonomic order is not recorded here, its neutral chemistry is a solid baseline for agriculture.

Sandy Textures Drive Water Movement

The soil is predominantly sand at 56.1%, balanced by 21.3% clay and 22.3% silt. This sandy makeup ensures the soil is easy to dig and work with throughout the year. It provides better aeration than the heavy clays found further north in the state.

Lower Water Retention and Organic Levels

At 1.34%, the organic matter content is below the Texas average of 1.66%. Similarly, the available water capacity of 0.129 in/in is slightly lower than the state average of 0.133 in/in. Gardeners should expect the soil to dry out fairly quickly during the peak of summer.

High Runoff Risk with Hydrologic Group D

Despite the high sand content, the soil is classified under Hydrologic Group D, which typically indicates very slow infiltration and high runoff potential. This can lead to surface pooling during heavy Texas downpours. Careful management of drainage is necessary for both farming and home construction.

Diverse Planting in Zone 9a

Zone 9a offers a warm climate where heat-loving plants like melons and squash will excel in your sandy soil. Because the water capacity is slightly lower, utilizing drip irrigation or mulching will help maintain consistent growth. Your neutral pH means you have a wide open palette for selecting your favorite plants.
