About Soil in Lincoln County, Colorado
Balanced Alkaline Plains Soil
Lincoln County's soil pH of 7.22 is slightly more alkaline than the national median of 6.5. This level is nearly identical to the Colorado average of 7.29, reflecting the consistent chemistry of the state's eastern plains.
High Sand for Easy Drainage
The soil is composed of 52.2% sand, 28.7% silt, and 18.3% clay. This sand-heavy mix provides excellent drainage and ease of workability, though it may require more frequent watering than heavier soils.
Consistent Water Capacity
Organic matter content is 1.53%, which trails the state average of 2.18%. However, the available water capacity of 0.136 in/in is almost exactly the same as the statewide average of 0.139.
Managing Water in Sandy Soil
Specific hydrologic groups are not listed, but the 52.2% sand content suggests that water moves quickly through the profile. This reduces the risk of root rot but makes nutrient retention a key focus for local farmers.
Plains-Hardy Growth in Zone 5b
In USDA Hardiness Zone 5b, Lincoln County provides a great environment for drought-resistant vegetables and grains. Start your garden today to make the most of the region's sunny and reliable summers.

Soil & Planting Advisory: Lincoln County
Soil Verdict
Lincoln 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
Lincoln County closely matches the Colorado average hardiness conditions.
