About Soil in Cooper County, Missouri
Near Neutral pH Profile
Cooper County boasts a soil pH of 6.47, nearly hitting the national target of 6.5 exactly. This near-neutral acidity level makes it one of the most chemically balanced soil profiles in the state of Missouri.
Dominated by Fine Silt
The soil is comprised of 65.4% silt and 19.5% clay, creating a dense but nutrient-rich environment for roots. While specific texture records are limited, the 14.7% sand suggests a soil that holds water and nutrients exceptionally well.
Top-Tier Water Capacity
At 0.210 in/in, the available water capacity is significantly higher than the state average of 0.183. Even with organic matter at 2.28%, the soil's ability to store water provides a massive advantage during the summer heat.
Substantial Moisture Potential
While official drainage and hydrologic group data are currently limited for this area, the high soil score of 76.6 indicates high productivity. Growers should monitor local moisture levels as the high silt content often leads to slow natural drainage.
Ready for Heavy Production
Sitting in zone 6b, this soil is perfect for moisture-loving crops like melons and leafy greens. With a soil score far exceeding the state average, Cooper County is a premier location to establish a productive family garden.

What type of soil does Cooper County have?
Cooper County's soil is classified as Silt Loam. This indicates the relative proportions of sand, silt, and clay — 15% sand, 65% silt, and 20% clay. Loamy soils hold moisture well and support a wide range of plants.
Is Cooper County's soil acidic or alkaline?
Cooper County's soil has a pH of 6.5, which is moderately acidic. This range suits many crops and is common across much of the eastern US.
What is the drainage class for Cooper County?
Cooper County has a dominant drainage class of "Subaqueous." Moderate drainage allows adequate moisture retention while still permitting excess water to drain over time.
What crops or plants grow well in Cooper County's soil?
Based on Cooper County's Silt Loam texture, pH of 6.5, and Subaqueous, the soil is well suited for vegetables, grains, and most field crops, row crops and vegetable gardens.
What USDA soil order is found in Cooper County?
The dominant USDA soil order for Cooper County is not currently available in our dataset.
Soil & Planting Advisory: Cooper County
Soil Verdict
Cooper 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
Cooper County closely matches the Missouri average hardiness conditions.
