About Soil in Wabash County, Illinois
Acidic Alfisols of the Wabash Valley
Wabash County is characterized by Alfisols, which are typically fertile forest soils. The average pH is 6.22, more acidic than both the national median of 6.5 and the Illinois state average of 6.39. This suggests the land may benefit from lime applications for certain traditional crops.
Classic Silty Clay Loam Texture
The soil is a silty clay loam consisting of 59.3% silt, 20.5% clay, and 20.2% sand. This specific texture is prized for its ability to hold water while still allowing for air circulation to the roots. It offers a balanced medium that resists the extreme compaction of pure clay.
Solid Water Capacity with Lower Organic Matter
Organic matter measures 1.95%, which is lower than the Illinois average of 2.94%. Despite this, the available water capacity of 0.203 in/in sits right at the state average. This indicates the soil is excellent at storing water, though it may need organic additions to reach its full nutrient potential.
Well-Drained Ground for Healthy Roots
The dominant drainage class is well drained, ensuring that water moves through the profile without drowning plant roots. It belongs to hydrologic group C, which implies a slow infiltration rate when the soil is thoroughly wet. This combination is generally favorable for building foundations and agriculture alike.
Thriving in a Zone 6b Environment
With a 6b hardiness rating, Wabash County supports a long and productive growing season. These well-drained Alfisols are excellent for fruit trees and deep-rooted perennials. Grab some compost and start your garden today to take advantage of this reliable southern Illinois land.
