Data Story

About Soil in Mille Lacs County, Minnesota

Acidic Entisols of the North

Mille Lacs County is dominated by Entisols with a very acidic pH of 4.75. This is significantly lower than both the national median of 6.5 and the state average of 6.21. This acidic profile is characteristic of younger, less developed soils in forested regions.

Light and Silty Composition

The soil consists of 44.1% sand and 39.8% silt, with a very low 9.3% clay content. This makes the soil exceptionally light and easy to dig, but it lacks the natural nutrient-holding capacity of clay. Management here requires focusing on building and maintaining the soil's organic structure.

Surprising Organic Wealth

Despite its acidity, the soil contains 15.68% organic matter, far exceeding the state average of 9.90%. This drives a high available water capacity of 0.220 in/in, the best in this group. This moisture retention helps compensate for the lack of clay.

Naturally Well-Drained Land

The soil is classified as well-drained, which is expected given the high sand and silt content. This prevents waterlogging and makes it suitable for various building and farming projects. However, the 64.6 soil score reflects the challenges posed by the extreme acidity.

Acid-Loving Plants Thrive in 4a

In Hardiness Zone 4a, this soil is a paradise for acid-loving plants like blueberries, hydrangeas, and conifers. Conventional gardeners will need to use lime to raise the pH for standard vegetables. It is a unique landscape that rewards those who plant for the local conditions.
