Data Story

About Soil in Hickory County, Missouri

Gravelly Entisols Define the Landscape

The dominant soil in Hickory County is a gravelly silty clay classified under the Entisols order. With a pH of 5.86, these soils are notably more acidic than the national median of 6.5 and the state average of 6.09. This youthful soil order often requires careful management to build up productive layers.

Silt-Rich Mix with Rockier Textures

Hickory County soil is composed of 58.4% silt and 18.8% clay, though the gravelly texture significantly influences its workability. The 19.5% sand content provides some drainage, but the high silt percentage can lead to surface crusting. This mix is common in the Ozark region and presents unique challenges for traditional tilling.

Tough Conditions for Water and Nutrients

Organic matter is low at 2.11%, trailing far behind the Missouri average of 4.74%. The Available Water Capacity is 0.172 in/in, which is below the state average of 0.183 in/in, meaning these soils dry out faster. Growers will find that these soils need frequent watering and consistent organic inputs to remain productive.

Well Drained with Slow Infiltration

The soil is classified as well drained, yet it belongs to hydrologic group C, which indicates a slow rate of water transmission. This combination means while the soil doesn't stay soggy, it doesn't absorb heavy rains quickly, leading to potential runoff. Builders should note these characteristics when planning septic systems or foundations.

Hardy Planting in Zone 6b

Hickory County sits in Hardiness Zone 6b, providing a versatile climate for fruit trees and perennial herbs. While the soil score of 48.9 is below the state average, raised beds can easily bypass the gravelly texture. Start a backyard orchard today to take advantage of the well-drained slopes.
