Data Story

About Soil in Holt County, Nebraska

Sandy Loams of the Northern Plains

Holt County's soil score of 53.5 sits just below the Nebraska average, reflecting its unique northern geography. The average pH of 6.65 is nearly identical to the national median of 6.5, providing a balanced chemical environment. These Mollisols are historically significant, representing the transition into the Nebraska Sandhills.

High Sand Content Loam

The soil is classified as loam, but it leans heavily on the sandy side with 62.8% sand. Silt makes up 22.1% of the profile, while clay is low at 12.8%. This creates a coarse texture that is easy to dig but can be vulnerable to wind erosion if left exposed.

Decent Organic Matter, Low Water Storage

At 3.10%, the organic matter is healthy, nearly reaching the Nebraska state average of 3.32%. However, the available water capacity is quite low at 0.133 in/in, well below the state average of 0.172. Plants in this soil will need more frequent, shallow watering to stay hydrated.

Slow Subsurface Drainage Challenges

While the soil is surface-classified as well drained, it surprisingly falls into hydrologic group D. This indicates that while the top layer is sandy, deeper layers may restrict water movement, leading to high runoff potential during heavy rains. It is a complex system that requires careful management during wet seasons.

Cold-Hardy Planting in Zone 5a

Holt County is in hardiness zone 5a, meaning you should select plants that can survive harsh, cold winters. Potatoes and cool-weather greens thrive in this loose, sandy loam. Focus on building up your soil with mulch to improve that low water capacity for a more successful harvest.

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.
