About Soil in Scott County, Illinois
Neutral and Balanced Soil Chemistry
Scott County maintains a healthy soil pH of 6.52, which aligns closely with the national median of 6.5. This is slightly less acidic than the Illinois state average of 6.39, offering a versatile base for many plant species. Even without specific taxonomic data, the chemical profile suggests a highly productive environment.
Sandier Mix for Better Drainage
At 26.7% sand, Scott County has one of the higher sand concentrations in the region, paired with 54.1% silt and 19.2% clay. This extra sand provides better aeration and faster drainage than neighboring counties with heavier silt profiles. It makes the soil easier to work with early in the spring when other fields might be too wet.
Moderate Organic Matter and Water Storage
The soil contains 2.13% organic matter, surpassing the national average of 2.0%. However, the available water capacity of 0.189 in/in is lower than the state average of 0.204. While this means the soil may dry out faster, it also warms up more quickly for early planting.
Fast-Warming Soils with Active Hydrology
While specific drainage classes are unavailable, the 26.7% sand content suggests a more active hydrologic group than typical Illinois silt-loams. This composition allows for better vertical water movement, reducing the risk of standing water in gardens. It is a preferred profile for crops that dislike 'wet feet' or stagnant conditions.
Early Starts Possible in Zone 6a
Zone 6a weather and sandier soil mean Scott County gardeners can often plant earlier than their neighbors. The soil is excellent for melons, asparagus, and other crops that thrive in well-drained, warmer ground. It is time to get outside and take advantage of this workable, neutral soil.
