About Soil in Douglas County, Wisconsin
Young, Acidic Soils of the North
Douglas County features Entisols with an average pH of 4.73, making it one of the most acidic regions in the state. This level is significantly lower than the state average of 5.63 and the national median of 6.5. These young soils are still developing and reflect the rugged, northern environment near Lake Superior.
Sand-Driven and Low in Clay
The soil contains 42.3% sand and 21.5% silt, with a very low clay content of only 6.4%. This composition allows for easy water movement through the upper layers of the earth. The low clay levels mean the soil lacks the 'stickiness' found in southern Wisconsin, remaining loose and light.
Massive Organic Matter Reserves
Douglas County boasts an incredible 25.37% organic matter, more than double the state average and 12 times the national average. This extreme organic richness leads to a very high available water capacity of 0.250 in/in. It is a sponge-like soil that holds onto every drop of moisture and nutrient available.
Well Drained Despite High Retention
The soil is classified as well-drained, meaning it avoids the swampy conditions one might expect from such high organic matter. This balance of high water storage and good drainage is rare and highly beneficial for northern plant species. It provides a stable but moist environment for both forests and gardens.
Cold-Hardy Gardening in Zone 4a
With a short growing season in Zone 4a, gardeners should focus on blueberries and cranberries that love the county's natural acidity. The high organic matter is perfect for growing massive yields of potatoes and root crops. Harness this rich, northern earth by planting early-season varieties that can handle the cool nights.

Is Douglas County's soil acidic or alkaline?
Douglas County's soil has a low pH of 4.7, which is strongly acidic. Acidic soils benefit from lime applications to raise pH and improve nutrient availability.
What is the drainage class for Douglas County?
Douglas County has a dominant drainage class of "Well drained." Well-drained soils allow excess water to move through quickly, reducing waterlogging risk and supporting most field and garden crops.
What crops or plants grow well in Douglas County's soil?
Based on Douglas County's Loam texture, pH of 4.7, and Well drained, the soil is well suited for acid-loving plants like blueberries and azaleas, row crops and vegetable gardens, most annual and perennial crops.
