Heavy Silt and Clay

The soil is composed of 33.3% sand, 40.4% silt, and 24.1% clay. This heavy silt and clay presence creates a dense soil that retains water and nutrients exceptionally well.

High Capacity for Growth

The 7.30% organic matter is robust, while the available water capacity of 0.201 in/in exceeds the state average. This combination provides a great natural buffer against dry spells.

Superior Physical Scores

While specific drainage classes are unavailable, the high soil score of 87.5 reflects superior physical properties. The balance of silt and clay suggests a stable but dense environment for foundations.

Long Seasons in Zone 5a

As part of Zone 5a, you can enjoy a longer growing season for tomatoes, peppers, and fruit trees. Your soil's neutral pH makes it some of the most versatile gardening land in Minnesota.

Soil & Planting Advisory: Blue Earth County

Soil Verdict

Blue Earth County is in USDA hardiness zone 5a, a cold climate zone. where winter lows can reach -20°F. Freeze-thaw cycles are moderate; soil biology slows in winter but recovers reliably in spring, supporting a broad range of plants.

Planting Guidance

A wide plant palette is possible: deciduous trees, most shrubs, cool-season vegetables, and many perennials thrive here. 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

Moderate freeze-thaw cycles naturally aerate the soil but can also cause compaction in clay-heavy areas; annual core aeration is beneficial. Organic matter amendments decompose at a moderate pace — aim for 3-5% organic content for optimal fertility. When soil temperatures drop below freezing, microbial nitrogen cycling stops; spring fertilization is more effective than late-fall application.

Regional Context

Blue Earth County is somewhat warmer than the Minnesota statewide average.
