Data Story
About Soil in Hughes County, Oklahoma
The Mollisol Grasslands of Hughes
Hughes County is characterized by Mollisols, the dark, nutrient-rich soils often associated with historic grasslands. However, the current pH of 5.50 is quite acidic compared to the national 6.5 median. Despite the high-quality soil order, the county receives a soil score of 27.0, indicating some modern management hurdles.
Silt Loam for Smooth Workability
The dominant texture is silt loam, consisting of 45.9% sand and 28.7% silt with a low clay content of 16.1%. This creates a soil that is exceptionally easy to work and doesn't get as waterlogged as heavier clay soils. It provides an excellent medium for root expansion in young plants.
Consistent Moisture for Native Growth
The available water capacity is 0.143 in/in, nearly matching the state average of 0.144 in/in. Organic matter is 1.47%, which is higher than some western neighbors but still below the state average of 1.72%. This balance supports stable growth for native Oklahoma prairie grasses.
Moderate Drainage and Group B Hydrology
Hughes County soils are typically 'Well drained' and fall into Hydrologic Group B. This moderate infiltration rate helps prevent the standing water issues seen in Group D soils. It makes the land more versatile for varied uses, from agricultural fields to residential gardens.
Prime Zone 7b Growing Conditions
The 7b hardiness zone and silt loam texture make this a great spot for root vegetables like carrots and potatoes. Because the soil is acidic, gardeners should test their pH before planting alkaline-loving greens like kale or spinach. It’s a rewarding environment for anyone looking to cultivate a diverse backyard homestead.
