Data Story
About Soil in Perry County, Arkansas
Weathered Ultisols of the River Valley
Perry County's landscape is dominated by Ultisols, which are highly weathered forest soils with an average pH of 5.53. This level is more acidic than the national median of 6.5 but typical for the region's soil score of 32.8. These soils often require lime and phosphorus amendments to maximize their agricultural potential.
Productive loam provides balance
The dominant texture is loam, a desirable mix of 41.6% sand, 40.9% silt, and 17.5% clay. This specific ratio is often considered the 'gold standard' for workability, as it holds moisture well without becoming waterlogged. It provides a stable structure that supports both small garden beds and large-scale farming.
Strong water capacity despite low organic matter
While organic matter is low at 1.67% compared to the state average of 4.15%, the soil excels in moisture retention. The available water capacity of 0.151 in/in actually exceeds the state average of 0.148. This means the soil is naturally resilient during the short droughts common in an Arkansas summer.
Well-drained soils in Group B
Perry County features well-drained soils and belongs to Hydrologic Group B, which offers moderate infiltration rates. This is an ideal middle ground that allows for efficient drainage while still keeping moisture available for crops. These conditions are excellent for building stable structures and maintaining healthy, aerated root zones.
Vibrant growing in Zone 8a
The Zone 8a climate combined with loamy soil makes Perry County a great place for diverse crops like corn, squash, and tomatoes. The well-drained nature of the land also supports healthy orchards and vineyards. If you have been waiting to start a garden, this loam is one of the most forgiving starting points in the state.
