About Soil in Vernon County, Wisconsin
High-Quality Silt Loams
Vernon County boasts an average soil pH of 6.11, making it one of the closest in the state to the national median of 6.5. This pH level is significantly higher than the Wisconsin average of 5.63, creating a very hospitable environment for many vegetables. Taxonomic data is currently missing, but the chemical profile is among the state's best.
Silt Dominance in the Driftless
The soil is characterized by a high silt content of 52.0%, paired with 32.0% sand and 14.0% clay. This silt-heavy mix is prized for its ability to hold nutrients while remaining easy to till and plant. It represents a classic high-productivity soil texture typical of prime Wisconsin farmland.
Lean Organic Matter, Reliable Water Storage
Organic matter content is 3.49%, which is lower than the state average but still above the national average of 2.0%. Despite the lower organic levels, the available water capacity of 0.198 in/in is nearly identical to the state average of 0.204 in/in. This efficiency allows the soil to remain productive even with fewer biological inputs.
Stability on the Hillside
While specific drainage classes are not listed, the high silt and clay content helps the soil retain moisture longer than sandier counties. This provides a buffer against drought but may require attention to avoid compaction during wet years. Builders should note that this soil holds its structure well.
Thriving in Zone 5a
Vernon County resides in USDA Hardiness Zone 5a, offering a slightly longer growing season than its northern neighbors. The high silt content and favorable pH make it an ideal spot for organic vegetable production and orchards. With a top-tier soil score of 70.5, this is some of the finest ground in the state.
