About Soil in Clare County, Michigan
Rich Acidic Mollisols of Central Michigan
Clare County is dominated by Mollisols with a pH of 4.40, which is well below the national median of 6.5. These soils are typically nutrient-rich but require lime to manage the high acidity for most crops.
A Balanced Loam with Sandy Roots
The soil is a loamy mix consisting of 53.3% sand and 11.2% clay. The 18.0% silt helps bridge the gap, creating a structure that is easy for roots to penetrate while maintaining some stability.
Strong Organic Content Above State Averages
At 25.98%, the organic matter content exceeds the state average of 19.76%. The available water capacity of 0.201 in/in sits right at the state baseline, indicating reliable water availability during the growing season.
Managing Saturated Ground and Runoff
Classified as poorly drained and belonging to hydrologic group B/D, this soil can stay soggy after heavy rains. Farmers and builders should plan for drainage solutions to prevent standing water issues.
Thriving in a Zone 5a Climate
The Zone 5a climate pairs well with Clare's high-organic Mollisols for growing perennials and cool-season vegetables. It is a great environment for a productive garden if you monitor soil moisture levels.
