Data Story
About Soil in Wabash County, Indiana
Wabash County’s Rich Alfisol Heritage
Wabash County features a high soil score of 79.3, anchored by versatile Alfisols and a silt loam texture. Its average pH of 6.19 sits comfortably above the Indiana state average of 6.08.
A Gritty and Productive Mix
The soil contains 35.2% sand, providing excellent aeration and structure for root development. This is balanced by 41.0% silt and 17.9% clay, creating a soil that drains well while retaining essential nutrients.
Exceptional Organic Matter Levels
At 6.26%, the organic matter in Wabash is far above the state average of 4.90% and triples the national average. The available water capacity of 0.202 in/in matches the state average exactly, ensuring consistent moisture availability.
Natural Drainage for Robust Fields
The county's soils are primarily well drained and belong to hydrologic group C. This allows for efficient water movement through the soil profile, reducing the likelihood of root diseases during wet Indiana springs.
Fertile Potential in Zone 6a
Wabash is a powerhouse for agriculture, particularly for crops that demand high organic content like corn and squash. The gritty, well-drained soil is also perfect for establishing fruit orchards and berry patches.

Hydrologic Group
Group C — Moderate-High Runoff
Soils with slow infiltration rates, often with a layer that impedes downward water movement. Higher clay content restricts drainage.
Drainage Class
Well drained
Water is removed from the soil readily but not rapidly. Optimal for most plants and construction.

What type of soil does Wabash County have?
Wabash County's soil is classified as Silt loam. This indicates the relative proportions of sand, silt, and clay — 35% sand, 41% silt, and 18% clay. Loamy soils hold moisture well and support a wide range of plants.
Is Wabash County's soil acidic or alkaline?
Wabash County's soil has a pH of 6.2, which is moderately acidic. This range suits many crops and is common across much of the eastern US.
What is the drainage class for Wabash County?
Wabash County has a dominant drainage class of "Well drained." Well-drained soils allow excess water to move through quickly, reducing waterlogging risk and supporting most field and garden crops.
What crops or plants grow well in Wabash County's soil?
Based on Wabash County's Silt loam texture, pH of 6.2, and Well drained, the soil is well suited for vegetables, grains, and most field crops, row crops and vegetable gardens, most annual and perennial crops.
What USDA soil order is found in Wabash County?
Wabash County's dominant soil order is Alfisols. Alfisols are moderate to high base-status soils with a clay-enriched subsoil. They support productive forests and cropland across temperate regions.
Soil & Planting Advisory: Wabash County
Soil Verdict
Wabash County is in USDA hardiness zone 6a, a moderate climate zone. where winter lows can reach -10°F. Freeze-thaw cycles are moderate; soil biology slows in winter but recovers reliably in spring, supporting a broad range of plants.
Planting Guidance
A wide plant palette is possible: deciduous trees, most shrubs, cool-season vegetables, and many perennials thrive here. Winter protection (mulch, burlap wraps) helps push the zone boundary for desired species. Always match plant selections to the specific microclimate of your property — low spots, slopes, and wind exposure can shift effective hardiness by half a zone.
Soil Implications
Moderate freeze-thaw cycles naturally aerate the soil but can also cause compaction in clay-heavy areas; annual core aeration is beneficial. Organic matter amendments decompose at a moderate pace — aim for 3-5% organic content for optimal fertility. When soil temperatures drop below freezing, microbial nitrogen cycling stops; spring fertilization is more effective than late-fall application.
Regional Context
Wabash County closely matches the Indiana average hardiness conditions.
