Data Story

About Soil in Crawford County, Illinois

Balanced pH near national norms

Crawford County soils maintain an average pH of 6.40, sitting very close to the national median of 6.5. While specific taxonomic data is limited here, this near-neutral acidity supports a wide range of biological activity.

Silt-heavy texture with moderate sand

The soil contains 60.3% silt and 20.7% sand, making it relatively easy to work. A 19.0% clay component provides enough structure to hold essential nutrients without becoming overly heavy or compacted.

Moderate organic matter levels

Organic matter sits at 2.08%, which exceeds the national average but falls below the Illinois state average of 2.94%. The available water capacity of 0.190 in/in suggests slightly lower moisture retention than many neighboring counties.

Moderate drainage potential despite missing data

Specific drainage classes are not recorded for this profile, but the high silt content typically allows for steady water movement. Gardeners should monitor for saturation during heavy spring rains to protect young root systems.

Warm growing season in Zone 6b

Hardiness zone 6b supports heat-loving crops like peppers and melons. Your soil score of 65.5 provides a solid foundation, especially if you supplement with compost to boost organic levels.
