Data Story
About Soil in Acadia Parish, Louisiana
Acidic and Silty Acadia Soils
Acadia Parish features an average pH of 5.44, making it notably more acidic than the national median of 6.5. While taxonomic data remains unclassified, these acidic levels typically require lime amendments for optimal crop growth. Local growers manage this chemistry to support the region's historic agricultural roots.
High Silt Content Drives Texture
The soil composition is dominated by 60.7% silt, balanced by 20.2% clay and 14.5% sand. This high silt percentage creates a smooth, floury texture that offers good workability but can be prone to erosion. The moderate clay levels help the soil hold onto nutrients more effectively than sandy alternatives.
Strong Water Capacity Despite Lower Organic Matter
The soil contains 2.58% organic matter, which beats the national average of 2.0% but lags behind the Louisiana average of 6.38%. However, its available water capacity of 0.192 in/in is superior to the state average of 0.182 in/in. This allows the land to store moisture efficiently for plants during dry spells.
Moisture Retention in a Humid Climate
Specific drainage and hydrologic classifications are currently unlisted for this parish. However, the high silt content and strong water capacity suggest that the land retains moisture well. Gardeners should still monitor for standing water following the heavy rains common in South Louisiana.
Abundant Growth in Zone 9a
Located in USDA Hardiness Zone 9a, Acadia Parish is ideal for heat-tolerant vegetables and citrus trees. The combination of silty soil and high moisture capacity supports productive rice and soybean crops. Home gardeners should feel encouraged to start a plot, as the long growing season offers ample opportunity for success.
