Data Story
About Soil in Carroll County, New Hampshire
Mountain Soil with Deep Character
Specific pH and taxonomic data are limited for this rugged stretch of New Hampshire. Regional trends suggest soils are much more acidic than the national median of 6.5. This acidity is a hallmark of the forested slopes throughout the White Mountains.
Coarse Textures in the White Mountains
The precise mix of sand, silt, and clay for Carroll County is not currently documented. Most mountain soils here tend to be rocky and coarse, favoring trees over traditional row crops. Local workability depends heavily on the specific elevation and glacial history of the plot.
Unmapped Nutrient Reservoirs
Data for organic matter and available water capacity is currently unavailable for Carroll. Without these numbers, it is difficult to compare the county's growing potential against the state average of 32.6% organic matter. Local growers must use soil tests to find their specific fertility needs.
Steep Slopes and Swift Runoff
The drainage class for the county is unclassified, but the topography ensures rapid water movement. Building and farming here require a close eye on slope stability and natural runoff patterns. Managing water effectively is the key to preventing erosion on these steep hillsides.
Resilient Gardening in Zone 5a
The 5a hardiness zone is a challenging but rewarding environment for dedicated gardeners. Cold-tolerant crops like blueberries and cranberries thrive in the local mountain climate. Start your garden with raised beds to maximize the shorter growing season.

Soil & Planting Advisory: Carroll County
Soil Verdict
Carroll County is in USDA hardiness zone 5a, a cold climate zone. where winter lows can reach -20°F. Freeze-thaw cycles are moderate; soil biology slows in winter but recovers reliably in spring, supporting a broad range of plants.
Planting Guidance
A wide plant palette is possible: deciduous trees, most shrubs, cool-season vegetables, and many perennials thrive here. 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
Moderate freeze-thaw cycles naturally aerate the soil but can also cause compaction in clay-heavy areas; annual core aeration is beneficial. Organic matter amendments decompose at a moderate pace — aim for 3-5% organic content for optimal fertility. When soil temperatures drop below freezing, microbial nitrogen cycling stops; spring fertilization is more effective than late-fall application.
Regional Context
Carroll County closely matches the New Hampshire average hardiness conditions. The zone range of 5a-5b within the county means soil and planting decisions should account for local elevation and topography.
