About Soil in Floyd County, Indiana
Southern Silt and Moderate Acidity
Floyd County soils have a pH of 5.97, leaning slightly more acidic than the state average of 6.08. This profile results in a soil score of 65.5, which is common for the rolling hills of Southern Indiana. These conditions require careful monitoring for plants sensitive to low pH levels.
A Landscape Dominated by Silt
The soil is extremely silt-heavy at 70.8%, with only 10.6% sand and 18.6% clay. This high silt concentration creates a very smooth texture that holds onto moisture tightly. It is less abrasive than sandy soils but can become slippery and prone to erosion on slopes.
Excellent Water Reserves
Available water capacity is a strong 0.212 in/in, which is better than the Indiana average of 0.202. Organic matter is low at 2.12%, matching the national average but trailing the state average. This soil effectively stores the rain it receives, providing a buffer for your plants.
Hydrology of the Silt Plains
While specific drainage class data is not available, soils with 70% silt typically exhibit moderate to slow drainage. The lack of sand means water moves slowly through the soil profile. Gardeners on slopes should be mindful of runoff during the heavy rains common to Floyd County.
Extended Growing in Zone 6b
Enjoy the warmer climate of zone 6b, where the high water capacity supports a long growing season. Silt-heavy soils are excellent for leafy greens and many native Indiana perennials. Start a compost pile today to help enrich these moisture-rich southern soils.
