Data Story

About Soil in Pushmataha County, Oklahoma

Acidic Sands of the Southeast

Pushmataha County has a very acidic average pH of 5.32, which is significantly lower than the national median of 6.5. This low pH is characteristic of the region’s heavily leached soils and high rainfall. While data on taxonomic order is limited, the acidic profile is a primary constraint for local agriculture.

Sand-Dominant Soil Profiles

The soil is dominated by sand at 50.4%, with 28.2% silt and 14.4% clay. This high sand content creates a very loose, porous texture that allows for fast initial water entry but poor long-term retention. It is generally low in natural nutrients because they wash through the coarse grains easily.

Low Organic Matter and Water Storage

Organic matter is quite low at 1.03%, well below the state average of 1.72%. Additionally, the available water capacity of 0.129 in/in is lower than the Oklahoma average of 0.144 in/in. These factors contribute to the county's low soil score of 14.6, reflecting the challenges for intensive farming.

High Runoff Despite Sandy Texture

Despite the high sand content, the county is categorized in hydrologic group D, indicating high runoff potential during heavy rains. This often occurs because of shallow bedrock or restrictive layers beneath the sandy surface. Effective water management is critical to prevent erosion in this hilly terrain.

Timber and Pine in Zone 8a

Pushmataha County is in the warm 8a hardiness zone, making it ideal for southern pines and acid-loving forestry. The sandy, acidic soil is better suited for timber and specialized fruit like blackberries than for typical row crops. Use raised beds with imported soil to have the most success with a vegetable garden.
