About Soil in Carter County, Missouri
Acidic Profiles in Carter County
Carter County soils are notably acidic with an average pH of 5.16, falling well below the national median of 6.5. This unique chemistry results in a lower soil score of 39.8, as many regional taxonomic data points remain unclassified.
High Organic Silt Mix
The soil contains 35.8% silt and 17.9% sand, creating a light texture despite the lack of a dominant formal classification. A low clay content of 7.9% means these soils may struggle with structural stability compared to the state's heavier clays.
Massive Organic Matter Reserves
The county boasts an extraordinary organic matter content of 27.23%, dwarfing the state average of 4.74%. However, the available water capacity is quite low at 0.109 in/in, meaning water passes through quickly despite the rich carbon content.
Challenges of Subaqueous Drainage
Classified as subaqueous, these soils are often saturated or influenced by nearby water bodies. This drainage class requires specialized management for any construction or traditional farming efforts to avoid persistent dampness.
Gardening in Warmer Zone 7a
Carter County sits in Hardiness Zone 7a, allowing for a longer growing season than its northern neighbors. Acid-loving plants like blueberries or azaleas will thrive in this naturally low-pH environment.
