About Soil in White County, Indiana

Deep, dark Mollisols of the prairie

White County features Mollisols, the world's most productive agricultural soils known for their thick, dark surfaces. The average pH of 6.20 is slightly more acidic than the national median but remains higher than the Indiana average of 6.08. These soils provide a rich chemical environment for intensive crop production.

A unique clay loam balance

With a high sand content of 43.0% and 39.0% silt, these clay loams offer better aeration than typical Indiana soils. The 14.4% clay fraction is relatively low, which helps prevent the heavy compaction often seen in the Midwest. This mix ensures the soil is easy to till while still holding its shape.

Exceptional organic matter levels

White County boasts 5.45% organic matter, surpassing the state average of 4.90% and more than doubling the national average. Despite this richness, available water capacity is slightly lower than the state benchmark at 0.189 in/in. The high organic content acts as a natural sponge and nutrient powerhouse for plants.

Navigating poorly drained prairie soils

Classified as poorly drained with a B/D hydrologic group, these soils require active management to prevent saturation. The high organic content helps, but the natural drainage class means water can linger after heavy rains. This makes drainage tiles a common and necessary feature for local agricultural success.

Productive gardening in zone 6a

The high organic matter in White County makes it a dream for growing heavy feeders like tomatoes, peppers, and corn. Because these Mollisols are so fertile, your garden will require fewer fertilizers than in other regions. Take advantage of this prairie heritage and start your spring planting early.
