About Soil in Lincoln Parish, Louisiana
Sandy and acidic northern soil
Lincoln Parish soil is notably acidic with a pH of 5.35, falling below the national median of 6.5. This acidity is typical for the region but lower than the state average of 5.74.
Dominantly sandy textures
A high 66.7% sand content makes this soil very loose and easy to cultivate. However, with only 9.9% clay, the soil has limited ability to hold onto nutrients and water compared to siltier parishes.
Low organic matter and capacity
Organic matter is quite low at 1.64%, which is below both the national 2.0% and state 6.38% averages. This results in a low available water capacity of 0.125 in/in, making the soil prone to drying out quickly.
Runoff risks in Group D
Lincoln Parish belongs to Hydrologic Group D, indicating very slow infiltration rates despite the sandy surface. This creates a high risk for runoff and erosion during the heavy rain events common in North Louisiana.
Success with the right plants in 8b
Root crops and pine trees thrive in these sandy, acidic conditions within zone 8b. Gardeners should prioritize frequent watering and consistent mulching to overcome the soil's natural drainage and low water capacity.
