Data Story
About Soil in Red River Parish, Louisiana
Moderately Acidic Soils in Red River
Red River Parish features a soil pH of 6.04, which sits comfortably between the state average of 5.74 and the national median of 6.5. While local taxonomy data is limited, this acidity level provides a versatile foundation for most Southern crops. The soil is less acidic than many neighbors, offering a slightly more balanced chemical profile.
A Silty Foundation for Farming
The soil contains 43.2% silt and 32.9% sand, creating a medium-textured profile that is easier to work than heavy clays. With a clay content of 24.0%, the land maintains a decent balance between drainage and nutrient retention. This mix allows for manageable tillage while providing enough body to support plant roots.
Lower Organic Matter but Stable Capacity
Organic matter measures 1.76%, which is below both the state average of 6.38% and the national average of 2.0%. Despite this, the available water capacity of 0.171 in/in remains close to the state benchmark of 0.182 in/in. Growers may need to focus on adding compost or cover crops to boost natural fertility.
Runoff Challenges in Hydrologic Group D
The land belongs to hydrologic group D, which indicates a high runoff potential and slow water movement through the profile. While specific drainage class data is missing, this group suggests that heavy rains may lead to ponding. Proper grading or raised beds are essential for managing water in this landscape.
Abundant Growth in Zone 8b
Located in hardiness zone 8b, Red River Parish is ideal for heat-loving crops like okra, peppers, and southern peas. The silty soil supports robust vegetable gardens if supplemented with organic nutrients. Start your garden this spring to take advantage of the long, productive growing season.
