Data Story

About Soil in Brown County, Wisconsin

Brown County’s Rich Histosol Identity

Brown County features a pH of 6.46, which is nearly identical to the national median of 6.5 and much higher than the Wisconsin average of 5.63. These are primarily Histosols, known for their dark, carbon-rich profiles.

A Heavy 'Muck' Composition

The dominant texture is classified as Muck, consisting of 42.3% sand and a substantial 15.0% clay. This higher clay percentage provides much better nutrient-holding capacity than the sandier northern counties.

Consistent Water for Crops

Organic matter is 5.53%, which is below the state average of 11.02% but more than double the national average of 2.0%. An available water capacity of 0.192 in/in closely follows the state average, offering stable growing conditions.

Very Poorly Drained Lowlands

The soil is very poorly drained and belongs to hydrologic group B/D, meaning a high water table is common. This makes drainage management a priority for builders and large-scale farmers alike.

Prime Growth in Zone 5b

The warmer Zone 5b climate and near-neutral pH allow for a huge variety of plants, from tomatoes to fruit trees. If you can manage the wetness, this is some of the most productive soil in the state.

Is Brown County's soil acidic or alkaline?

Brown County's soil has a pH of 6.5, which is moderately acidic. This range suits many crops and is common across much of the eastern US.

What is the drainage class for Brown County?

What crops or plants grow well in Brown County's soil?

Based on Brown County's Muck texture, pH of 6.5, and Very poorly drained, the soil is well suited for vegetables, grains, and most field crops, rice, cranberries, and other water-tolerant species.

What USDA soil order is found in Brown County?

Brown County's dominant soil order is Histosols. Histosols are organic soils (peatlands and bogs) with very high organic matter content. They form in wet, poorly drained environments.
