About Soil in Jefferson County, Oklahoma
Classic Oklahoma Soil Near the Red River
Jefferson County soils maintain a pH of 6.03, which aligns almost perfectly with the Oklahoma state average of 6.06. This level is slightly more acidic than the national median of 6.5. Because dominant taxonomic data is unavailable, gardeners should rely on local pH tests to guide their lime applications.
Sandy Profiles Influence Local Hydrology
The soil is comprised of 46.4% sand and 16.1% clay, offering a coarse texture that handles water quickly. This mix is often influenced by its proximity to water-heavy riparian zones along the southern border. The 28.9% silt content helps provide enough structure to keep nutrients from leaching too fast.
Strong Water Retention for Dry Spells
Jefferson County boasts an available water capacity of 0.146 in/in, which exceeds the state average of 0.144. While organic matter is 1.57%—trailing the national 2.0% benchmark—the soil holds moisture effectively. This trait is a vital asset for maintaining pastures and crops during Oklahoma’s frequent dry stretches.
High Runoff Potential in Wet Seasons
Falling into hydrologic group D, this soil presents a high runoff potential and very slow infiltration when thoroughly wet. While specific drainage class data is missing, this classification suggests a risk of standing water during heavy rains. Proper site grading is essential for any local construction or gardening project.
Southern Growth in Hardiness Zone 8a
As a zone 8a region, Jefferson County enjoys a long growing season that supports everything from pecans to watermelons. The sandy soil is particularly forgiving for root vegetables and heat-loving perennials. It is a fantastic place to establish a productive home orchard or market garden.
