About Soil in Adams County, North Dakota
Slightly Alkaline Soils of the Southwest
Adams County features an average pH of 6.96, which is more acidic than the North Dakota state average of 7.18. This level remains higher than the 6.5 national median, providing a slightly alkaline foundation for local land use. While specific taxonomic data is unavailable, the chemical profile suggests a stable mineral environment.
A Balanced Sand and Silt Blend
The soil composition consists of 41.7% sand, 36.3% silt, and 22.1% clay. This distribution creates a workable texture that balances aeration with necessary structural body. It allows for decent root penetration while maintaining enough clay for nutrient storage.
Steady Moisture for Arid Plains
Organic matter stands at 3.69%, significantly beating the 2.0% national average but trailing the 4.69% state mark. The available water capacity is 0.183 in/in, which is very close to the state average of 0.186. This helps plants survive the dry spells typical of the western plains.
Natural Drainage and Soil Permeability
Specific drainage class and hydrologic group data are not available for this area. However, the 41.7% sand content suggests the soil likely moves water more efficiently than heavy clay regions. This prevents excessive waterlogging during the spring thaw.
Hardy Growing in Zone 4b
With a USDA Hardiness Zone of 4b, your garden can support robust grains and cool-season vegetables. The overall soil score of 63.2 perfectly matches the state average, indicating reliable productivity for any new gardener. Consider starting with flax or hardy wheat varieties to take advantage of this soil.
