Data Story
About Soil in Benson County, North Dakota
Mineral-Rich Soils Near Devils Lake Basin
Benson County’s soil averages a pH of 7.27, which is slightly more alkaline than the state average of 7.18. This exceeds the national median of 6.5 significantly, reflecting a high mineral content. These levels are common in the north-central glaciated plains.
Sandy Texture for Easy Workability
At 44.2% sand, these soils are easier to till and work than many of their eastern neighbors. Silt accounts for 35.5% and clay for 18.8% of the mix. This lighter composition allows for excellent aeration and quick warming in the spring.
Exceptional Organic Matter Levels
The organic matter content is an impressive 5.37%, surpassing both the state average of 4.69% and the national 2.0%. With an available water capacity of 0.185 in/in, the soil holds onto moisture nearly as well as the state's top performers. This combination creates a high potential for crop yields.
Well-Aerated Hydrological Profile
Specific drainage class data is unavailable, but the high sand percentage generally points to a naturally well-draining environment. This reduces the risk of root rot for sensitive plants during heavy rain events. The soil is well-suited for irrigation if needed.
Abundant Growth in Zone 4a
Benson County is located in Hardiness Zone 4a, perfect for root vegetables and hardy grains. The soil score of 62.6 is nearly identical to the state average of 63.2, proving its reliability. It is a fantastic place to build a high-producing home garden.

Soil & Planting Advisory: Benson County
Soil Verdict
Benson County is in USDA hardiness zone 4a, a cold climate zone. where winter lows can reach -30°F. Soils here experience deep freeze cycles that can disrupt structure, kill shallow roots, and slow microbial activity for months each year.
Planting Guidance
Focus on cold-hardy perennials, native grasses, and conifers. The short growing window favors plants with low heat requirements. With extreme winter lows, any marginally hardy plants need heavy mulch and wind protection. Always match plant selections to the specific microclimate of your property — low spots, slopes, and wind exposure can shift effective hardiness by half a zone.
Soil Implications
Deep winter freezing can create soil heaving that pushes shallow-rooted plants out of the ground; add 3-4 inches of organic mulch each fall. Soil drainage is critical — frozen, waterlogged soil kills roots faster than cold alone. When soil temperatures drop below freezing, microbial nitrogen cycling stops; spring fertilization is more effective than late-fall application.
Regional Context
Benson County closely matches the North Dakota average hardiness conditions.
