Data Story

About Soil in Uintah County, Utah

High pH levels define Uintah's profile

The average pH is 7.91, significantly higher than the 6.5 national median. This alkalinity reflects the arid conditions of the Uinta Basin and influences nutrient availability.

Sand dominates this desert soil mix

With 45.1% sand and 19.2% clay, the soil offers decent structure but limited moisture grip. Silt fills the remaining 30.9% to provide a balanced texture for local farmers.

Organic matter beats national benchmarks

The 3.83% organic matter content exceeds the 2.0% national average, though it trails Utah's 7.59% average. Uintah's soil score of 27.8 reflects its challenges compared to the 41.8 state average.

Drainage data is currently unrecorded

While specific drainage classes aren't in the database, the high sand content generally indicates fast-draining conditions. Builders and farmers should perform on-site percolation tests to confirm water movement.

Hardy crops thrive in Zone 5b

Beets, carrots, and potatoes handle the alkaline soil and cold winters exceptionally well. Start your high-desert garden with soil amendments to balance the pH for more sensitive plants.

Soil & Planting Advisory: Uintah County

Soil Verdict

Uintah County is in USDA hardiness zone 5b, a cold climate zone. where winter lows can reach -15°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

Uintah County is somewhat cooler than the Utah statewide average. The zone range of 5b-6a within the county means soil and planting decisions should account for local elevation and topography.
