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.

Hydrologic Group
Group B — Moderate Runoff
Moderately deep, moderately well-drained soils with moderate infiltration rates. Good balance of drainage and water retention.
Drainage Class
Poorly drained
Water is removed so slowly that the soil is wet at or near the surface much of the year. Drainage improvement usually needed.

Browse Soil AmendmentsFrequently Asked Questions
What type of soil does Clare County have?
Clare County's soil is classified as Loam. This indicates the relative proportions of sand, silt, and clay — 53% sand, 18% silt, and 11% clay. Loamy soils hold moisture well and support a wide range of plants.
Is Clare County's soil acidic or alkaline?
Clare County's soil has a low pH of 4.4, which is strongly acidic. Acidic soils benefit from lime applications to raise pH and improve nutrient availability.
What is the drainage class for Clare County?
Clare County has a dominant drainage class of "Poorly drained." Poorly drained soils retain water for extended periods, which can limit crop choices and may require tile drainage or raised beds.
What crops or plants grow well in Clare County's soil?
Based on Clare County's Loam texture, pH of 4.4, and Poorly drained, the soil is well suited for acid-loving plants like blueberries and azaleas, row crops and vegetable gardens, rice, cranberries, and other water-tolerant species.
What USDA soil order is found in Clare County?
Clare County's dominant soil order is Mollisols. Mollisols are fertile, dark-colored soils that formed under grassland vegetation. They are among the most productive agricultural soils in the world.
Soil & Planting Advisory: Clare County
Soil Verdict
Clare County is in USDA hardiness zone 5a, a cold climate zone. where winter lows can reach -20°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. With extreme winter lows, any marginally hardy plants need heavy mulch and wind protection. 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
Clare County closely matches the Michigan average hardiness conditions. The zone range of 5a-5b within the county means soil and planting decisions should account for local elevation and topography.
