Data Story
About Soil in Natchitoches Parish, Louisiana
A Typical Louisiana Acidic Profile
Natchitoches Parish maintains an average soil pH of 5.79, almost exactly matching the Louisiana state average. This level is notably more acidic than the national median of 6.5, often requiring lime for optimal crop yields.
Sandy Texture with Fast Drainage
The soil composition is 44.5% sand, which is quite high for the region, balanced by 33.0% silt and 22.4% clay. This sand-heavy mix allows for easier tilling and faster drainage than the heavier clays found eastward.
Lower Organic Reserves
At 1.76%, organic matter is lower than the national 2.0% average and well below the state average of 6.38%. The available water capacity of 0.156 in/in suggests the soil may dry out faster than the state average of 0.182 in/in.
High Runoff Potential
Classified in hydrologic group D, these soils have a very high runoff potential when thoroughly wet. This suggests that despite the sandy texture, deep drainage is restricted, which is a critical consideration for site planning.
Planting in Zone 9a
The long growing season in Zone 9a is perfect for heat-tolerant varieties of peppers and tomatoes. Gardeners should prioritize adding compost to boost the relatively low organic matter levels.
