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.

Frequently Asked Questions
What type of soil does Fulton County have?
Fulton County's soil is classified as Loam. This indicates the relative proportions of sand, silt, and clay — 56% sand, 21% silt, and 9% clay. Loamy soils hold moisture well and support a wide range of plants.
Is Fulton County's soil acidic or alkaline?
Fulton County's soil has a low pH of 5.4, which is strongly acidic. Acidic soils benefit from lime applications to raise pH and improve nutrient availability.
What is the drainage class for Fulton County?
Fulton County has a dominant drainage class of "Poorly drained." Poorly drained soils retain water for extended periods, which can limit crop choices and may require tile drainage or raised beds.
What crops or plants grow well in Fulton County's soil?
Based on Fulton County's Loam texture, pH of 5.4, and Poorly drained, the soil is well suited for acid-loving plants like blueberries and azaleas, row crops and vegetable gardens, rice, cranberries, and other water-tolerant species.
What USDA soil order is found in Fulton County?
