About Soil in Cass County, Missouri
A Stable Base in Cass
Cass County maintains an average pH of 6.21, which sits comfortably between the Missouri state average of 6.09 and the national median of 6.5. This near-neutral acidity level provides a versatile foundation for a wide range of plant life.
The Power of Silt
Silt dominates the landscape at 60.7%, paired with 26.2% clay and a low 12.4% sand content. This mix creates a smooth, heavy soil that excels at holding onto vital nutrients but can be slow to dry after a spring rain.
Excellent Moisture Storage
The available water capacity is 0.200 in/in, significantly higher than the Missouri average of 0.183 in/in. While the 2.70% organic matter is lower than the state average, the high water retention makes it very resilient during dry spells.
Adaptable Hydrology Potential
While specific drainage class and hydrologic group data are limited for this county, the high silt and clay percentages suggest a need for surface management. The soil score of 69.9 indicates high overall quality for diverse agricultural uses.
Start Your Garden in 6b
Hardiness Zone 6b allows for a great variety of perennials and hardy vegetables. Utilize this high-capacity soil to grow deep-rooted crops like tomatoes and peppers that benefit from the steady moisture levels.

Soil & Planting Advisory: Cass County
Soil Verdict
Cass County is in USDA hardiness zone 6b, a moderate climate zone. where winter lows can reach -5°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
Cass County closely matches the Missouri average hardiness conditions.
