Data Story
About Soil in Atlantic County, New Jersey
Acidic Coastal Soils Define the Landscape
Atlantic County's soil is notably acidic with an average pH of 5.18, though it sits well above the state average of 4.24. While still more acidic than the national median of 6.5, these coastal soils reflect the unique chemistry of the South Jersey region.
Sand Dominates the County Profile
The ground here is dominated by sand, which makes up 66.5% of the soil profile. This high sand content ensures excellent workability but means the soil struggles to hold onto water and essential nutrients compared to siltier regions.
High Organic Matter with Quick Drainage
Organic matter is a high point at 14.19%, dwarfing the national average of 2.0% but falling slightly behind the state average. However, a low available water capacity of 0.116 in/in means plants may need more frequent watering during dry spells.
Managing Saturated Soil Conditions
Much of the county features subaqueous drainage and belongs to hydrologic group D, indicating very slow infiltration rates when saturated. These conditions present significant challenges for traditional building and require specialized management for agricultural use.
Thriving in Hardiness Zone 7b
Gardeners in hardiness zone 7b can take advantage of long growing seasons to cultivate blueberries and cranberries, which thrive in acidic, sandy environments. Start your coastal garden today by selecting native plants that love the unique Pinelands-style soil.
