Data Story
About Soil in Kiowa County, Oklahoma
Granite Shadows and Neutral Soils
Kiowa County features a pH of 6.45, placing it nearly exactly at the national median of 6.5. This is significantly more alkaline than the Oklahoma state average of 6.06, making it some of the most chemically balanced soil in the region. Though taxonomic data is limited, the pH supports a wide range of botanical diversity.
A Balanced Mix of Sand and Clay
The soil is a balanced blend of 35.1% sand, 32.3% silt, and 20.0% clay. This proportion offers a good compromise between the drainage of sand and the nutrient-holding capacity of clay. It provides a stable base for both native grasses and cultivated row crops.
Moisture Management in a Dry Landscape
The available water capacity is 0.129 in/in, which is lower than the state average of 0.144. Organic matter is also modest at 1.34%, trailing the Oklahoma average of 1.72%. These numbers suggest that while the soil is chemically sound, it requires careful water management to thrive in the summer.
High Runoff Risk During Storms
This county's soil is categorized in hydrologic group D, indicating very slow infiltration rates and high runoff potential. Despite the balanced texture, the underlying soil structure likely restricts water movement during heavy rains. Managing water flow is essential to prevent soil loss in this rugged landscape.
Southwest Beauty in Zone 7b
Kiowa County’s zone 7b climate and neutral soil are perfect for drought-resistant natives and hardy vegetables like squash. The balanced soil texture is easy for home gardeners to work with throughout the seasons. With a little supplemental irrigation, your garden can become a local oasis.
