About Soil in Lee County, Arkansas
Optimal pH Levels in Lee County
Lee County features an average pH of 6.14, making it one of the less acidic counties in the state. This level is much closer to the national median of 6.5 than the Arkansas state average of 5.56. This favorable chemistry makes it easier to grow a wide variety of plants without heavy lime applications.
High Silt and Clay Mix
The soil composition is very high in silt at 56.6%, with 21.9% clay and 21.5% sand. This mixture results in a heavy, nutrient-dense soil that can hold significant moisture but may be prone to compaction. The low sand percentage means the soil will stay cool and moist longer than sandier neighboring regions.
Excellent Water Retention
Available water capacity is impressive at 0.185 in/in, well above the Arkansas average of 0.148 in/in. However, organic matter is relatively low at 1.62%, which is below the state's 4.15% benchmark. Focusing on building up organic material will turn this high water-capacity soil into a powerhouse for growth.
Managing Dense Soil Structure
While specific drainage classes are not provided, the high silt and clay content suggests a soil that drains slowly. This can be beneficial during dry Arkansas summers but requires careful management during the wet winter months. Planning for proper runoff is essential for maintaining healthy roots in this dense soil.
Extended Growth in Zone 8a
The 8a Hardiness Zone provides a long, warm season that pair perfectly with Lee County's moisture-retaining soil. It is an ideal spot for thirsty crops like corn or lush ornamental gardens. Your garden will thrive here if you focus on adding compost to boost that organic matter.
