About Soil in Hancock County, Iowa

Slightly Alkaline Soils Near the National Median

Hancock County features an average soil pH of 6.72, which sits just above the national median of 6.5. This measurement is higher than the Iowa state average of 6.43, providing a less acidic environment for local crops. While specific taxonomic classifications are currently unavailable, the overall soil score of 81.8 is significantly higher than the state average.

A Balanced Blend of Sand and Silt

The soil contains 34.8% sand, 37.2% silt, and 23.9% clay. This relatively even distribution supports good workability while maintaining enough clay to hold necessary nutrients. The sand content helps prevent total compaction, allowing roots to penetrate the soil more easily.

Exceptional Organic Matter Levels

This county boasts an impressive 7.53% organic matter, nearly double the Iowa state average of 3.81%. The available water capacity reaches 0.200 in/in, which is higher than the state mean of 0.195. These figures indicate a highly fertile landscape that retains moisture and nutrients effectively.

High Soil Score Suggests Reliable Stability

Specific drainage class and hydrologic group data are unavailable for this region. However, the high soil score of 81.8 suggests that the land is exceptionally well-suited for intensive agricultural production. Farmers should still monitor local fields for ponding given the high organic content and water capacity.

Ready for Hardiness Zone 5a Success

In USDA Hardiness Zone 5a, these high-fertility soils are perfect for growing corn, soybeans, and hearty cool-season vegetables. With organic matter levels far exceeding national averages, your garden will require less supplemental fertilizer than most. Start your beds early to take advantage of this rich, nutrient-dense ground.
