About Soil in Comanche County, Oklahoma
Acidic soils near the Wichita Mountains
Comanche County features a pH of 5.83, which is more acidic than the state average of 6.06 and the national median of 6.5. This acidity is common for the region and often requires lime for pasture and crop optimization. The soil score of 29.9 indicates it is slightly more challenging than the state average of 35.3.
Sandy-silt texture with variable structure
The soil contains 34.6% sand and 31.9% silt, providing a relatively light texture that is generally easy to work. With a clay content of 18.5%, it has enough body to hold nutrients but may dry out quickly during the wind-heavy days of Southwest Oklahoma. The 'variable' texture indicates the diverse topography of the county.
Below average water capacity and matter
At 1.48%, the organic matter content is slightly below the state average of 1.72%. The available water capacity is 0.133 in/in, which is also below the state average of 0.144 in/in. These levels mean that drought management is particularly important for successful growing in this county.
High runoff and slow infiltration
Hydrologic Group D soils here mean that water moves very slowly through the soil profile when it is wet. This can lead to flash flooding and high runoff rates during the intense thunderstorms typical of the plains. Land management should focus on minimizing erosion and capturing what little rainfall occurs.
Hardy gardening in zone 7b
The 7b hardiness zone allows for a long summer of growing heat-resistant crops like cantaloupes and okra. Because the soil's water capacity is lower, using mulch is vital to keep roots cool and moist. It is a great place to start a garden if you prioritize water conservation and soil enrichment.
