About Soil in Franklin Parish, Louisiana
Sharp acidity in Franklin soils
With a pH of 5.43, Franklin Parish soils are notably more acidic than both the state average and the 6.5 national median. This low pH level is a key factor in determining which crops will succeed without significant soil amendments.
Silt-heavy mix limits air pockets
The soil contains 60.7% silt and 24.4% clay, making it one of the siltier regions in the state. Only 14.9% sand is present, which can lead to compaction and limited aeration for deep-rooted plants.
Excellent water capacity despite low organic matter
The available water capacity of 0.197 in/in is well above the Louisiana average, providing a great buffer against drought. Organic matter remains low at 1.82%, suggesting a need for compost to improve soil health.
Surface water management is key
While specific drainage data is unavailable, the high silt and clay levels suggest water moves slowly through the profile. Proper grading is essential in this parish to prevent water from standing in fields or around foundations.
Hardy growth in Zone 8b
Zone 8b offers a perfect climate for sweet potatoes and peppers, which thrive in Franklin's moisture-holding soils. With a little lime to raise the pH, your backyard garden can become a high-yielding oasis.
