About Soil in Nemaha County, Nebraska

Premier Soil Quality in Nemaha County

Nemaha County features an impressive soil score of 66.4, far exceeding the Nebraska state average of 58.9. The average pH is 6.64, which is very close to the ideal national median of 6.5. This slightly acidic to neutral range is perfect for the diverse agriculture of Southeast Nebraska.

Silt-Rich Profiles and Heavy Clays

This county has a distinct composition of 54.1% silt and 28.5% clay, with only 15.7% sand. This high silt and clay content creates a heavy, nutrient-dense soil that holds onto minerals extremely well. While it can be harder to till when wet, its ability to support plant life is superior.

Top-Tier Moisture Storage for Gardens

The available water capacity is 0.185 in/in, significantly higher than the state average of 0.172 and the highest in this group. Organic matter is 2.65%, comfortably above the national 2.0% average. These factors combine to create a resilient soil that can withstand heatwaves by holding deep moisture reserves.

Managing Heavier Soils and Runoff

The low sand content and high clay levels suggest slower drainage and a higher potential for runoff compared to western counties. This requires careful erosion control on sloped land to protect the valuable topsoil. For builders, the clay content means soil may expand or contract, requiring robust foundation designs.

Bountiful Harvests in Zone 5b

Nemaha County is a gardener's dream in Zone 5b, capable of producing massive yields of corn, beans, and heavy-feeding vegetables.
