About Soil in Roseau County, Minnesota
Acidic and Rich Northern Soils
Roseau County features a soil pH of 6.05, which is more acidic than the national median of 6.5. This level is also slightly below the Minnesota state average of 6.21. Many northern forest plants and specific crops thrive in these slightly sour conditions.
Sandy Texture with High Porosity
The soil contains 45.9% sand, 33.7% silt, and only 11.4% clay. This sandy composition allows for rapid drainage and prevents waterlogging during heavy rains. However, it requires careful nutrient management as water moves through the profile quickly.
Exceptional Organic Matter Levels
At 20.47%, the organic matter in Roseau is more than double the state average of 9.90%. This extreme richness drives an available water capacity of 0.222 in/in, which is among the highest in the region. This organic abundance offsets the sandy texture to keep plants hydrated.
High-Performing Northern Landscapes
The county boasts an impressive soil score of 86.9, far exceeding the state average of 73.0.
