About Soil in Falls County, Texas
Falls County's Rich Mollisol Identity
The county features nutrient-rich Mollisols with a dominant loam texture. At 7.23, the pH is slightly more alkaline than the national median of 6.5 and sits above the Texas average of 7.09. This balance supports high natural fertility for regional agriculture.
A Balanced Blend of Sand and Clay
The soil contains a nearly equal mix of 37.1% sand, 31.6% silt, and 31.3% clay. This loamy profile offers excellent workability while retaining enough clay to hold onto essential plant nutrients. Gardeners find this texture easy to manage compared to heavier clay regions.
Water Storage Beats the State Average
Organic matter sits at 1.60%, trailing the national average of 2.0% but mirroring the Texas average. However, the available water capacity of 0.148 in/in exceeds the state average of 0.133, providing a reliable moisture reservoir for crops during dry spells.
Well Drained but High Runoff Risk
The land is classified as well drained, yet it belongs to hydrologic group D, which indicates high runoff potential when saturated. While water moves well through the profile, the heavy clay subsoil can limit infiltration during intense Texas thunderstorms. Proper site grading is essential for new construction projects here.
Thriving in Hardiness Zone 8b
Warm winters and loamy soils make Falls County ideal for heat-tolerant vegetables and stone fruits like peaches. With a soil score of 35.6, this land outperforms the state average of 28.8. Start your garden today to take advantage of these productive Central Texas conditions.
