About Soil in Ste. Genevieve County, Missouri
High-Quality Soils Along the River
Ste. Genevieve County earns a soil score of 67.9, outperforming much of the state. While the soil is somewhat acidic with a pH of 5.96, its high nutrient capacity makes it historically significant for agriculture.
The Power of Silt
With 59.0% silt and 16.8% clay, these soils are fine-textured and highly capable of holding nutrients. The relatively low sand content of 15.2% means the soil can be prone to compaction if worked while wet.
Rich in Natural Organic Matter
The county features an impressive 8.28% organic matter, nearly double the state average of 4.74%. This richness helps offset the slightly below-average water capacity of 0.178 in/in by improving soil structure.
Challenges of Saturated Soil
Classified as subaqueous, much of the county's soil profile is adapted to very wet conditions. This requires careful site selection for building and suggests a need for raised beds in some gardening scenarios.
Lush Growth in Zone 6b
The combination of high organic matter and a 6b hardiness zone is perfect for Missouri’s native pawpaws and pecans. Farmers and gardeners alike can capitalize on this fertility to produce high-yielding vegetable crops.
