About Soil in Muskogee County, Oklahoma
Productive Silt Loams in Muskogee
Muskogee County features Entisols with a dominant silt loam texture and an average pH of 5.60. While this is more acidic than the national median of 6.5, these soils are often quite productive with proper management. Entisols represent young soils that still retain much of the mineral character of their parent material.
High Silt Content for Better Texture
The soil profile is 37.3% silt, 35.6% sand, and 17.3% clay, creating a smooth, workable silt loam. This high silt fraction makes the soil feel floury to the touch and provides excellent surface area for nutrient exchange. It balances drainage and retention better than more sandy neighbors.
Strong Water Capacity for Dry Spells
The available water capacity of 0.152 in/in is higher than the Oklahoma state average of 0.144 in/in. Organic matter sits at 1.59%, which provides a solid baseline for biological activity in the soil. These factors combine to give Muskogee a resilient foundation for agriculture during hot Oklahoma summers.
Well-Drained Land with Moderate Runoff
Most of the county is well-drained but falls into hydrologic group C, suggesting somewhat slow infiltration when wet. This means while the soil usually stays aerated, heavy rain can lead to significant surface runoff. Proper terracing or cover cropping is recommended to protect the topsoil from erosion.
Abundant Growth in Zone 7b
Muskogee’s climate and silt-rich soil are perfect for growing corn, soybeans, and lush ornamental gardens. The 7b hardiness zone provides a long frost-free window for tomatoes and peppers to reach their full potential. Grab a shovel and start planting to take advantage of this fertile river-valley region.

Hydrologic Group
Group C — Moderate-High Runoff
Soils with slow infiltration rates, often with a layer that impedes downward water movement. Higher clay content restricts drainage.
Drainage Class
Well drained
Water is removed from the soil readily but not rapidly. Optimal for most plants and construction.
