Data Story
About Soil in Schoolcraft County, Michigan
Acidic Wetlands of the Upper Peninsula
Schoolcraft County presents a unique profile with an average pH of 4.47, making it far more acidic than the national median of 6.5. This high acidity is typical for the region's vast wetlands and peatlands. Because so much of the county is dominated by water-rich environments, standard taxonomic classifications are limited.
Minimal Mineral Content
The soil composition is unusually low in mineral particles, with only 16.1% sand, 7.3% silt, and a mere 1.0% clay. The dominant 'texture' is often simply water or muck, reflecting the county's boggy landscape. This means the soil lacks traditional structural workability but serves as a massive carbon sink.
Massive Organic Matter Reserves
Schoolcraft boasts an incredible 58.62% organic matter, nearly triple the Michigan state average of 19.76%. This leads to a very high available water capacity of 0.395 in/in, doubling the state benchmark. While nutrient-rich, the high acidity and saturation limit the types of plants that can thrive here.
A Landscape Defined by Water
Specific drainage and hydrologic group data are unavailable, as much of the area remains in a natural, saturated state. The high organic content acts like a sponge, holding vast amounts of water and influencing the entire regional ecosystem. Building and farming require specialized knowledge of these unique, wet conditions.
Toughened Growth in Zone 5a
The cooler 5a hardiness zone and acidic soils favor specialty crops like blueberries and cranberries. Traditional gardens will likely require lime to raise the pH and raised beds to escape the heavy saturation. However, the sheer organic wealth of this land offers a unique opportunity for native, acid-loving species.
