About Soil in Fulton County, Indiana

Acidic Mollisols define Fulton's loamy landscape

Fulton County features a dominant loam texture within the rich Mollisols taxonomic order. Its average pH of 5.35 sits significantly lower than the national median of 6.5, indicating highly acidic conditions. This acidity suggests a need for lime management to optimize local crop yields.

A sand-heavy mix with unique texture

The soil composition contains 56.2% sand, 20.6% silt, and 8.8% clay. This high sand content provides excellent workability and aeration but typically speeds up nutrient leaching. Fortunately, the massive organic matter content helps counteract the coarse sand grains.

Exceptional organic matter drives growing potential

At 11.68%, Fulton's organic matter is more than double the state average of 4.90%. Despite this richness, the available water capacity of 0.181 in/in falls slightly below the Indiana average of 0.202. This means the soil holds nutrients well but dries out faster than neighboring counties.

Poor drainage requires active water management

The county's soil is classified as poorly drained and falls into hydrologic group B/D. These conditions mean the ground stays saturated for long periods without intervention like tiling or raised beds. Builders and farmers must plan for slow runoff and potential seasonal ponding.

Productive gardening in Hardiness Zone 6a

With a 6a hardiness rating, Fulton is ideal for cool-season vegetables and hardy perennials. The high organic matter provides a fantastic base for heavy feeders like corn and squash. Start your garden today to take advantage of some of the most carbon-rich soil in the state.
