Data Story
About Soil in Elmore County, Alabama
Ancient Ultisols of the Coastal Plain
Elmore County features highly weathered Ultisols with an average pH of 5.28. This is slightly less acidic than the state average but remains far below the national median of 6.5. These soils represent a landscape shaped by long-term leaching and warm climate conditions.
The Sandy Loam Advantage
With a dominant sandy loam texture, the soil consists of 61.2% sand and only 13.9% clay. This mix provides excellent workability and rapid drainage for agricultural operations. The 24.5% silt content adds enough structure to prevent the soil from being purely erosive.
Low Organic Matter Challenges
At 1.30%, the organic matter in Elmore is notably lower than the 2.0% national average. The available water capacity of 0.125 in/in also falls below the state average of 0.138. This combination means frequent irrigation and cover cropping are essential to maintain soil health and productivity.
Well Drained for Building and Farming
Classified as well-drained and belonging to hydrologic group B, these soils move water efficiently through the profile. This makes Elmore County favorable for residential construction and septic systems compared to heavier clay regions. However, this high permeability means nutrients can leach away quickly after heavy rains.
Warm Seasons in Zone 8b
Situated in Zone 8b, Elmore County supports heat-tolerant crops like okra, sweet potatoes, and peaches. The sandy loam is perfect for root crops that struggle in heavier soils. Grab some compost to boost that organic matter and start your garden this weekend.
