About Soil in Greene County, Arkansas
Milder Acidity in Northeast Arkansas
Greene County features a pH of 5.75, making it less acidic than many of its Arkansas neighbors. While still below the national median of 6.5, it is more hospitable to a wider range of crops without immediate lime treatment. The soil score of 43.6 reflects a relatively high productivity potential.
Silt-Heavy Soils for Superior Texture
With a dominant silt content of 56.0%, these soils have a smooth, floury feel and excellent nutrient-holding power. The 27.4% sand and 16.6% clay provide a balanced structure that supports root growth. This silty profile is highly valued in the Delta region for its agricultural versatility.
High Water Capacity Drives Potential
Greene County boasts an available water capacity of 0.184 in/in, significantly higher than the state average of 0.148. Organic matter remains low at 1.51%, yet the soil's ability to hold water makes it resilient during dry spells. This combination makes it one of the more drought-resistant profiles in the state.
Complex Hydrology in the Delta
While specific drainage classes are not currently mapped, the high silt and clay levels suggest the soil requires careful management during wet seasons. The high available water capacity means these soils stay moist longer than sandy neighbors. This trait is a major benefit for consistent crop yields during the summer heat.
Optimal Growing in Zone 7b
In zone 7b, Greene County is perfectly suited for soybeans, corn, and large vegetable gardens. The superior water capacity gives you a head start on the growing season. With a little organic fertilizer, this silty ground can become one of the most productive patches in the state.
