Data Story
About Soil in Jackson Parish, Louisiana
Acidic soil in the northern piney woods
Jackson Parish features a highly acidic soil profile with an average pH of 5.23. This is significantly more acidic than the national median of 6.5 and falls below the Louisiana state average of 5.74. While taxonomic data is currently unclassified, the pH levels define the local growing environment.
Sandy ground with low clay content
The soil is predominantly sand at 55.3%, which makes it easy to work but less effective at holding nutrients. With only 14.0% clay and 30.7% silt, these soils typically drain quickly but may struggle to stay fertile without supplementation.
Modest organic levels and water retention
The parish holds 1.86% organic matter, which is slightly below the national 2.0% average and far behind the 6.38% state average. Consequently, the available water capacity of 0.137 in/in is lower than the state benchmark of 0.182 in/in, indicating lower drought resistance.
Slow infiltration in Hydrologic Group D
Despite the sandy texture, the soil belongs to Hydrologic Group D, suggesting it has a high runoff potential when thoroughly wet. While specific drainage class data is unavailable, this classification warns of potential pooling during heavy Louisiana rains.
Garden success in Zone 8b
The local climate in hardiness zone 8b pairs with sandy soils to favor acid-loving plants like blueberries and azaleas. With proper irrigation to manage the lower water capacity, Jackson Parish residents can maintain productive vegetable gardens.
