About Soil in Butler County, Iowa
Typical Iowa Silt and Acidity
Butler County features an average pH of 6.33, sitting just below the state average of 6.43 and the national median of 6.5. Its soil score of 71.9 is remarkably close to the Iowa-wide average of 72.9, making it a representative example of the state's prime farmland.

Balanced Loamy Composition
The soil is comprised of 44.2% silt, 34.1% sand, and 20.1% clay, creating a balanced loamy texture. This mix provides a good middle ground: the silt and clay retain nutrients, while the sand ensures enough pore space for oxygen to reach roots. It is a highly versatile medium that is neither too heavy nor too light.
Strong Organic Foundations
Butler County soils contain 4.58% organic matter, which is significantly higher than the state average of 3.81%. The available water capacity of 0.183 in/in is slightly lower than the state benchmark of 0.195 in/in, but the high organic matter helps compensate. This soil is naturally fertile and ready for high-intensity planting.
Moderate Hydrologic Function
Though formal drainage classifications are currently missing for this county, the 20.1% clay content suggests moderate drainage speeds. The soil is likely to stay moist without becoming waterlogged, provided the local topography allows for runoff. Homeowners should find this soil stable for most landscaping and small-scale construction.
