About Soil in Phelps County, Missouri

Acidic Ozark Soils in Phelps County

Phelps County soils are notably acidic with an average pH of 5.75, falling below both the state average of 6.09 and the national median of 6.5. While taxonomic data is limited for this area, the acidic profile is a signature characteristic of the Ozark Plateau region. This acidity influences how local plants access essential nutrients from the ground.

Silty Texture with Light Clay

The soil consists of 52.6% silt and 26.7% sand, creating a silty mix with a relatively low clay content of 13.2%. This high silt ratio ensures the ground is easy to work and manage for local growers. However, the moderate sand levels mean it may dry out faster than heavier clay soils found elsewhere in the state.

High Organic Matter, Lower Water Storage

Organic matter is impressively high at 5.85%, far exceeding the national average of 2.0% and the state average of 4.74%. Despite this richness, the available water capacity is just 0.151 in/in, which is lower than the Missouri average of 0.183 in/in. Gardeners should plan for supplemental irrigation during dry Ozark summers.

Saturated Subaqueous Drainage Patterns

The county features a subaqueous drainage class, indicating soils that are often saturated or influenced by proximity to water bodies. Because specific hydrologic group data is unavailable, land managers must observe local runoff carefully before building. Proper site selection is key to avoiding soggy foundations in these wet-leaning soils.

Cultivating Success in Zone 6b

In hardiness zone 6b, the high organic matter supports a wide range of native perennials and cool-season vegetables. While the soil is acidic, many Missouri natives thrive in these exact conditions. Start your garden today to take advantage of this naturally nutrient-dense ground.
