Data Story
About Soil in Jefferson County, Nebraska
Acidic Silts of the Southeast
Jefferson County features an average pH of 6.32, making it more acidic than the national median of 6.5. Its soil score of 69.3 is comfortably above the state average of 58.9, indicating strong productivity. These soils are characteristic of the rolling hills near the Kansas border.
Silt and Clay Heavy Profile
This county has a heavy soil profile with 51.3% silt and 26% clay, the highest clay content among its neighbors. Sand only makes up 22.7% of the mix, resulting in a dense soil that holds nutrients very well. However, this high clay content can make the ground difficult to work when it is too wet or too dry.
High Water Storage Potential
Organic matter is 2.65%, which is better than the national 2.0% average but under the state's 3.32%. The real strength here is the available water capacity of 0.194 in/in, which is well above the Nebraska average. This soil acts like a sponge, keeping moisture available to plants during late-summer dry spells.
Steady Hydrology in Silent Records
Specific drainage and hydrologic group classifications are currently missing from the digital record for this county. Given the 26% clay content, water likely moves more slowly through this soil than in the sandy western counties. Homeowners should check local site conditions for drainage before starting large construction projects.
Long Seasons in Zone 6a
As one of the warmer spots in Nebraska, zone 6a allows for a longer growing season and a wider variety of perennials. The high water capacity and slightly acidic pH are perfect for blueberries, tomatoes, and lush lawns. It is a fantastic place to start a diverse home orchard or a productive vegetable farm.
