Data Story

About Soil in Greenwood County, Kansas

Acidic and Fertile Tallgrass Soil

Greenwood County features an average pH of 6.31, making it more acidic than the state average and closer to the national median. This slight acidity is perfect for nutrient availability in many native plants. It represents some of the state's most productive territory with a soil score of 64.7.

Heavier Silt and Clay Mix

The soil is dominated by 57.2% silt and 28.6% clay, with very little sand at 14.2%. This heavy texture makes for excellent nutrient retention and a sturdy structure. However, it can be slower to drain and more difficult to work when wet.

Rich in Organic Matter

Organic matter is exceptionally high at 2.70%, far surpassing the state average of 2.22%. Available water capacity is also strong at 0.182 in/in. This combination creates a biological powerhouse for agriculture and gardening.

Slow Drainage and High Retention

Detailed drainage classes are not available, but the high clay and silt content suggest slower permeability. This land is designed to hold onto water, which is a benefit for grazing pastures. Be mindful of potential ponding in low-lying garden beds.

Lush Options in Zone 6b

Hardiness Zone 6b and high organic matter make this a gardener's paradise. It is an ideal spot for tomatoes, berries, and nutrient-hungry ornamentals. The soil is ready to support a diverse and thriving landscape.

Soil & Planting Advisory: Greenwood County

Soil Verdict

Greenwood County is in USDA hardiness zone 6b, a moderate climate zone. where winter lows can reach -5°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. Winter protection (mulch, burlap wraps) helps push the zone boundary for desired species. 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

Greenwood County closely matches the Kansas average hardiness conditions.
