About Soil in Fillmore County, Nebraska
Fillmore County's Rich Acidic Soil
Unlike most of its neighbors, Fillmore County has an acidic pH of 5.98, well below the state average of 6.79. This unique chemistry is paired with an impressive soil score of 76.9, among the best in Nebraska.
Silt-Dominant Growing Power
The soil contains a massive 59.8% silt and 24.4% clay, making it heavy and nutrient-dense. With only 13.0% sand, this soil is built for moisture retention rather than rapid drainage.
Exceptional Organic Wealth
Organic matter is a remarkable 4.66%, nearly double the national average. Coupled with a high available water capacity of 0.215 in/in, this is some of the most productive ground in the state.
Handling High Water Capacity
Although specific hydrologic groups are not listed, the high silt content suggests the soil stays wet longer than average. This makes the region excellent for agriculture but requires attention to drainage in backyard gardens.
Lush Growth in Zone 6a
In Hardiness Zone 6a, the combination of high organic matter and acidic soil is perfect for blueberries, hydrangeas, and diverse vegetables. This is a premier location for any aspiring gardener to start a patch.

Soil & Planting Advisory: Fillmore County
Soil Verdict
Fillmore County is in USDA hardiness zone 6a, a moderate climate zone. where winter lows can reach -10°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. Winter protection (mulch, burlap wraps) helps push the zone boundary for desired species. 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
Fillmore County is somewhat warmer than the Nebraska statewide average. The zone range of 5b-6a within the county means soil and planting decisions should account for local elevation and topography.
