Data Story
About Soil in Dickinson County, Michigan
Acidic Forest Soils of the North
Dickinson County has a pH of 4.96, making it more acidic than the state average of 5.30 and the national median of 6.5. This acidity is a hallmark of the forested regions in the Upper Peninsula.
Predominantly Sandy Soil Texture
The soil is 54.5% sand with a very low 5.3% clay content. This texture ensures the ground doesn't become sticky or heavy, but it may require amendments to help retain vital nutrients.
Solid Organic Levels with Moderate Storage
At 21.01%, the organic matter is slightly higher than the state average of 19.76%. However, the available water capacity of 0.194 in/in is just below the state norm, reflecting the soil's sandy nature.
Quick Water Movement Through Sand
Specific drainage data is missing, but the high sand percentage typically indicates rapid water movement. This minimizes mud issues but means gardens will likely need more frequent watering during dry spells.
Cold-Hardy Selection for Zone 4b
The 4b hardiness zone requires plants that can handle a shorter, cooler growing season. Focus on cold-hardy greens and native shrubs that thrive in naturally acidic, sandy environments.

Soil & Planting Advisory: Dickinson County
Soil Verdict
Dickinson County is in USDA hardiness zone 4b, a cold climate zone. where winter lows can reach -25°F. Soils here experience deep freeze cycles that can disrupt structure, kill shallow roots, and slow microbial activity for months each year.
Planting Guidance
Focus on cold-hardy perennials, native grasses, and conifers. The short growing window favors plants with low heat requirements. 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
Deep winter freezing can create soil heaving that pushes shallow-rooted plants out of the ground; add 3-4 inches of organic mulch each fall. Soil drainage is critical — frozen, waterlogged soil kills roots faster than cold alone. When soil temperatures drop below freezing, microbial nitrogen cycling stops; spring fertilization is more effective than late-fall application.
Regional Context
Dickinson County is somewhat cooler than the Michigan statewide average. The zone range of 4b-5a within the county means soil and planting decisions should account for local elevation and topography.
