Soil Quality in Karnes County

via SoilByCounty

Highly Alkaline South Texas Soils

Karnes County features an average pH of 7.32, making it significantly more alkaline than the national median of 6.5. This soil score of 31.1 is healthy, outperforming the state average of 28.8. Many local plants have adapted specifically to these higher lime levels.

Sandy Loam with High Clay Content

The soil consists of 44.6% sand, 22.0% silt, and 28.1% clay. This high clay percentage gives the soil excellent nutrient retention but can make it heavy and sticky when wet. You will need to wait for the right moisture levels before tilling to avoid clumping.

Rich Organic Matter for Texas

Infiltration Challenges in Group D

Classified in hydrologic group D, these soils have very slow infiltration rates when saturated. This means that during heavy Texas rains, the soil may struggle to absorb water quickly, leading to runoff. Consider using swales or rain gardens to manage water effectively on your property.

Intense heat and moderate rainfall

Alkaline clay-sand mix needs attention

The soil pH of 7.32 is higher than the ideal maximum of 7.0, which can limit the availability of certain nutrients. The mix of 44.6% sand and 28.1% clay provides a stable base but may require pH adjustment for peak performance.

Universal severe drought throughout the county

Every part of Karnes County is currently in severe drought, a condition that has persisted for the entire past year. Deep-soak your lawn once a week rather than light daily watering to encourage the roots to grow deeper.

Beat the heat with February planting

The final frost usually occurs by February 16, offering a long window for lawn establishment. Choose drought-tolerant varieties like Zoysia or Bermuda to withstand the 120 days of intense summer heat.
