About Soil in Sarpy County, Nebraska
Neutral Soils in a Developing Region
Sarpy County features a very balanced pH of 6.93, which is slightly higher than the national median of 6.5 and the state average of 6.79. This nearly neutral chemical profile is excellent for a wide variety of plants. It supports both agricultural uses and suburban landscaping efforts.
The Silt-Dominant Foundation
The soil is comprised of 56.2% silt and 25.2% clay, resulting in a smooth, productive texture. With only 18.6% sand, the soil retains its shape and moisture well without being overly gritty. This mix is common in the Missouri River valley areas of the state.
Balanced Organic Matter and Storage
Organic matter averages 2.27%, which stays above the national average of 2.0% but below the state’s 3.32%. The available water capacity is 0.184 in/in, outperforming the state average of 0.172. This provides a reliable buffer for plants during periods of low rainfall.
Consistent Moisture for Urban Landscapes
While specific drainage and hydrologic data are missing, the silt-heavy composition generally allows for steady, predictable water movement. These soils are reliable for home building and gardening because they don't dry out too rapidly. They provide a stable medium for the county's growing infrastructure.
Garden Success in Zone 6a
Sarpy County's 6a hardiness zone is perfect for everything from turfgrass to vegetable gardens and orchards. The neutral pH means you can plant immediately with very few chemical adjustments. It is a fantastic place to start a backyard garden or maintain a lush lawn.
