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.

A Balanced Blend of Sand and Silt

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.
