About Soil in Hampton County, South Carolina
Highly acidic profiles in Hampton County
Hampton County soil registers a pH of 5.00, which is significantly more acidic than the national median of 6.5 and lower than the state average. While specific taxonomic orders are not mapped here, the acidity suggests a landscape that requires lime for traditional gardening. Local growers must manage this low pH to unlock essential nutrients for plant growth.
A landscape dominated by sand
The soil composition is 77.6% sand, 11.9% silt, and 8.5% clay. This high sand content ensures fast drainage but limits the soil's ability to hold onto nutrients over time. You will find this ground easy to work and dig, though it dries out quickly during South Carolina's hot summers.
Impressive organic matter despite low water capacity
At 3.15%, the organic matter content is remarkably higher than the state average of 2.05% and the national average of 2.0%. However, the available water capacity is low at 0.097 in/in compared to the state average of 0.115 in/in. This means the soil is naturally rich in carbon but struggles to retain moisture for thirsty crops.
Limited data on local drainage patterns
Dominant drainage classes and hydrologic groups are currently unclassified for this county. Without specific drainage data, builders and farmers should perform site-specific perk tests to ensure proper water movement. The high sand percentage generally suggests rapid infiltration, but local pockets of clay could alter results.
