About Soil in Fulton County, Arkansas

Acidic Ultisols Define Fulton Soils

Fulton County features gravelly fine sandy loam and acidic Ultisols with a pH of 5.58. This level sits well below the national median of 6.5 but remains typical for the Arkansas state average. These weathered soils require careful pH management for optimal nutrient availability.

A Balanced Mix for Easy Workability

The soil contains 32.1% sand, 39.7% silt, and 11.7% clay. This specific composition makes the land easy to work while providing enough structure to prevent rapid erosion. The high silt content helps hold nutrients that the sand alone cannot.

Massive Organic Matter Boosts Fertility

Fulton's organic matter reaches a staggering 13.19%, dwarfing the state average of 4.15%. While available water capacity is slightly low at 0.114 in/in, the rich organic content creates an incredible foundation for plant health. This soil score of 47.2 ranks well above the state average of 37.7.

Well-Drained Land for Stable Growth

The county is primarily well drained and belongs to hydrologic group C. These properties mean water moves through the profile effectively, though infiltration rates are somewhat slow when the soil is saturated. This makes the land suitable for both diverse agriculture and stable construction.

Abundant Growth in Hardiness Zone 7a

The zone 7a climate paired with high organic matter supports everything from berries to lush pastures. Local gardeners should prioritize crops that thrive in slightly acidic conditions. Start your garden now to leverage some of the state's richest organic foundations.
