About Soil in Moultrie County, Illinois

Ideal pH Balance in Moultrie

Moultrie County soil reaches a pH of 6.50, hitting the national median exactly and sitting slightly above the state average. This ideal balance supports a thriving ecosystem of soil microbes and efficient nutrient cycling for crops.

Sturdy Structure and High Clay

The composition is defined by 62.3% silt and 24.6% clay, with sand making up 13.1% of the profile. This high clay and silt mix provides a sturdy structure that anchors roots firmly and resists the leaching of nutrients.

Fast-Drying Summer Soil

The soil contains 2.61% organic matter, outperforming the national average of 2.0%. Its available water capacity of 0.191 in/in is lower than the state benchmark, meaning the soil may dry out faster during the peak of the summer heat.

Check for Surface Runoff

Dominant drainage and hydrologic group data are not available for this county’s soil records. Residents should monitor their land for runoff patterns, as the high clay content can sometimes lead to slower surface water infiltration.

Perfect for Midwestern Staples

Falling within USDA Hardiness Zone 6a, Moultrie County is excellent for growing corn, beans, and summer squash. With a solid soil score of 72.4, this land is ready for you to plant a vibrant and productive garden.

Soil & Planting Advisory: Moultrie County

Soil Verdict

Moultrie 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

Moultrie County closely matches the Illinois average hardiness conditions.
