Data Story
About Soil in Clark County, Wisconsin
Deeply Acidic and Nutrient-Rich Earth
Clark County's soil is notably acidic with a pH of 5.24, falling well below both the state average and the national median of 6.5. Despite this acidity, the county maintains a soil score of 69.4, outperforming the state average of 68.2. This indicates a high-potential landscape that simply needs careful pH management.
Silt-Heavy and Light on Clay
The soil profile consists of 37.9% sand and 32.8% silt, with a very low clay content of 8.5%. This lack of clay makes the soil easy to till and prevents the heavy compaction often found in southern counties. However, the high sand ratio means water may move through the profile quickly.
Elite Organic Matter Levels
With a massive 16.26% organic matter content, Clark County exceeds both the state average of 11.02% and the national average of 2.0%. The available water capacity of 0.210 in/in also beats the state benchmark. This creates a fertile environment that naturally supports robust plant growth and moisture retention.
Managing High Moisture Retention
The high available water capacity suggests that while drainage data is limited, the soil holds onto moisture effectively. This trait is a boon for agriculture during late summer heat but can lead to soggy conditions in the spring. Proper site grading is essential for any building projects in these organic-rich soils.
Thriving in the Heart of Zone 4b
Zone 4b gardeners can leverage this high organic matter to grow heavy-feeding crops like pumpkins and squash. The acidic nature of the soil is also ideal for blueberries and other acid-loving shrubs. This is a prime location to build a productive home garden or a thriving orchard.
