Data Story

About Soil in Williams County, North Dakota

Neutral Soils in the Western Plains

Williams County features an average pH of 7.16, making it the most neutral soil among its neighbors and very close to the state average of 7.18. While still higher than the national 6.5 median, this profile provides an excellent chemical environment for nutrient uptake. This near-neutrality is a key advantage for western North Dakota farmers.

Extremely Gravelly Sand Foundations

The dominant texture here is extremely gravelly sand, containing 42.2% sand and just 21.1% clay. This coarse composition means the soil is very light and allows for rapid water movement through the ground. While it requires more frequent monitoring for moisture, it is very easy to work with hand tools or light machinery.

Productive Soils with Lower Water Storage

The organic matter content sits at 3.74%, which is lower than the state average but still nearly double the national 2.0% average. Because of its sandy nature, the available water capacity is 0.181 in/in, the lowest in this group. Growers here prioritize drought-resistant varieties to maximize the potential of this unique soil.

Excessively Drained for Fast Runoff

The soil is classified as excessively drained, meaning water moves through the profile very quickly. This prevents the ground from becoming waterlogged but can lead to dry conditions faster than in other counties. These drainage characteristics are excellent for construction and infrastructure, as the soil rarely holds excess moisture.

Gardening in the High Plains

In Zone 4a, the fast-draining sandy soil is perfect for drought-tolerant native plants and hardy grains. Gardeners should consider using mulch or raised beds to help retain moisture in the 3.74% organic matter soil. It is a fantastic place to grow berries and other perennials that prefer well-aerated ground.
