Data Story
About Soil in Lake County, Minnesota
Highly acidic soils of the North Shore
Lake County features an average soil pH of 4.87, making it much more acidic than the state average of 6.21. This puts the county well below the national median pH of 6.5. This low pH is typical of forest soils in northern Minnesota and dictates what types of vegetation will flourish naturally.
Silty textures with low clay presence
The soil composition is characterized by a high silt content of 47.4% and a sand content of 38.1%. With only 12.2% clay, the soil lacks the heavy, sticky feel of southern Minnesota farmland. This silty mix offers a soft texture that is relatively easy for roots to penetrate, though it can be susceptible to erosion.
Above-average organic richness and water storage
Lake County boasts 12.38% organic matter, which is higher than the state average of 9.90%. This translates to an available water capacity of 0.208 in/in, slightly beating the state benchmark of 0.199. These numbers indicate a soil that is excellent at holding onto nutrients and moisture in a rugged climate.
Variable drainage in a rocky terrain
Specific drainage and hydrologic group data are not listed, but the high silt content often leads to moderate drainage speeds. In this region, thin soils over bedrock can create localized drainage challenges or quick runoff. Managing water flow is essential for both forest health and residential development near Lake Superior.
Acid-loving plants thrive in zone 3b
The 3b hardiness zone and acidic soil are perfect for native berries, conifers, and rhododendrons. While the season is short, the high organic matter provides a great head start for cold-tolerant vegetables. Consider using raised beds to help the silty soil warm up faster during the cool spring months.
