About Soil in Scotts Bluff County, Nebraska
Alkaline Mollisols of the West
Scotts Bluff County features Mollisols with a notably alkaline pH of 7.44. This is much higher than the national median of 6.5 and the state average of 6.79. Such alkaline conditions are typical for the drier, western regions of Nebraska where minerals accumulate.
Loam Texture with a Sandy Lean
The dominant texture is loam, though it contains a high sand content of 57.6% and only 13.2% clay. This provides a coarse feel that allows for excellent aeration and root penetration. It is an ideal texture for crops that require well-drained conditions to prevent rot.
Low Organic Matter and Water Storage
Organic matter is relatively low at 1.49%, falling below the state average of 3.32% and the national 2.0%. The available water capacity is also lower than the state benchmark, measuring 0.156 in/in. Irrigation is essential here to compensate for the soil's lower storage capacity.
Moderate Drainage and Group B Hydrology
The soils are moderately well drained and belong to Hydrologic Group B. This indicates a moderate infiltration rate, making the soil efficient at soaking up irrigation water without excessive runoff. These characteristics make it a stable environment for both farming and construction.
Western Staples in Zone 5a
In hardiness zone 5a, sugar beets and dry beans are legendary successes for this soil type. Gardeners should focus on drought-tolerant species and use compost to improve the low organic matter. With the right water management, these soils are highly productive despite the dry climate.
