Data Story

About Soil in Dawes County, Nebraska

Young Entisols and Alkaline pH

Dawes County features Entisols, which are geologically young soils with limited horizon development. The average pH of 7.35 is quite alkaline, significantly exceeding the national median of 6.5 and state average of 6.79.

Sandy Loam for Fast Drainage

With a 46.3% sand and 34.0% silt composition, this loam is relatively coarse and well-aerated. The 17.7% clay content is low enough to prevent major compaction issues but high enough to provide basic structural stability.

Low Moisture Reserves

The available water capacity is 0.160 in/in, which is lower than the Nebraska average of 0.172. While organic matter at 2.18% is better than the national average, the soil's ability to store water for long periods is limited.

Well Drained with Slow Infiltration

The soil is well-drained but belongs to hydrologic group D, which indicates very slow infiltration rates when the ground is thoroughly wet. This paradox means water can run off the surface quickly during flash rains instead of soaking in.

Rugged Beauty in Zone 5a

Native prairie grasses and drought-resistant shrubs thrive in this zone 5a climate. Gardeners should prioritize mulching and drip irrigation to overcome the lower water capacity and the alkaline pH of the native soil.

Hydrologic Group

Group D — High Runoff

Clay soils with very slow infiltration rates. Highest runoff potential. These soils have a permanent high water table or are shallow over impervious material.

Runoff potential:High

Drainage Class

Well drained

Water is removed from the soil readily but not rapidly. Optimal for most plants and construction.
