Data Story
About Soil in Jackson County, Oklahoma
Neutral Soils in Oklahoma's Cotton Belt
Jackson County features a variable soil texture with a neutral pH of 6.67. This is slightly higher than the national median of 6.5 and significantly more alkaline than the Oklahoma state average of 6.06. While taxonomic order data is limited, the soil's chemistry is well-balanced for the region.
A Gritty Mix for Better Aeration
The soil contains 43.9% sand and 18.3% clay, creating a relatively light profile that resists compaction. With silt making up 26.6% of the mix, the soil remains workable for heavy machinery. This high sand content promotes root breathability but may require more frequent watering.
Lower Organic Matter Requires Management
At 1.11%, the organic matter content is well below the national average of 2.0% and the state average of 1.72%. The available water capacity of 0.122 in/in is also lower than the state benchmark of 0.144. Growers often find that adding compost or cover crops is essential to boost productivity here.
Well-Drained Ground with Moderate Runoff
The soil is classified as well drained, which is ideal for preventing root rot in sensitive crops. However, it belongs to hydrologic group C, indicating a moderately high runoff potential when saturated. Farmers and builders should account for slow water infiltration during heavy Great Plains thunderstorms.
Warm-Season Success in Zone 7b
Jackson County sits in hardiness zone 7b, where cotton and heat-tolerant sorghum dominate the landscape. The neutral pH is perfect for a diverse home garden featuring tomatoes, peppers, and okra. Start your seeds early to take full advantage of the long, sun-drenched growing season.
