Data Story
About Soil in Rusk County, Wisconsin
Highly acidic Northwoods forest soil
Rusk County has an average soil pH of 4.93, which is significantly lower than the state average of 5.63. This level of acidity is typical for the region but requires amendments for non-native plant species.
Balanced sand and silt proportions
The soil is composed of 34.8% sand and 33.5% silt, with a low clay content of 7.0%. This creates a permeable profile that allows for deep root penetration.
Massive organic matter reserves
Rusk County features 23.01% organic matter, nearly twelve times the national average. Coupled with an available water capacity of 0.251 in/in, this soil holds onto moisture and nutrients exceptionally well.
Exceptional water retention capabilities
Though specific drainage classes aren't listed, the high 0.251 water capacity suggests these soils remain hydrated through the season. This is a major benefit for maintaining greenery during the warmer summer months.
Cold-hardy crops for Zone 4a
A hardiness zone of 4a means a shorter season, but the 67.3 soil score ensures quality growth. Focus on acid-loving plants like cranberries or evergreens to work with your natural soil chemistry.

Soil & Planting Advisory: Rusk County
Soil Verdict
Rusk 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
Rusk County is somewhat cooler than the Wisconsin statewide average. The zone range of 4a-4b within the county means soil and planting decisions should account for local elevation and topography.
