McDowell County has an average soil pH of 5.12, which is nearly identical to the North Carolina average but lower than the 6.5 national median. The county earns a soil score of 35.4, indicating relatively healthy land for the region.
A Gritty Composition for Better Airflow
The soil is comprised of 52.4% sand, 26.4% silt, and 14.7% clay. This majority-sand mix allows for excellent root aeration and prevents the heavy compaction often found in clay-heavy regions.
Rich Organic Matter and Average Water Retention
At 6.53%, the organic matter content is significantly higher than the state average of 5.12%. The available water capacity of 0.128 in/in is slightly lower than the state benchmark, meaning organic amendments can help improve moisture holding.
Navigating Mountain Hydrology
Though specific hydrologic groups are not listed in this dataset, the high sand content generally leads to moderate to fast drainage. This makes the soil well-suited for building and farming on sloped terrains where water runoff is a concern.
