About Soil in Cape May County, New Jersey

The State's Most Acidic Coastal Ground

Cape May County possesses very acidic soil with an average pH of 4.01. This is significantly lower than the national median of 6.5 and even falls below the New Jersey state average of 4.24.

Coastal Sands Meet Heavy Silt

The soil composition is 66.4% sand, providing the gritty texture characteristic of the state's southern peninsula. Silt at 20.6% helps provide some structure, but the overall mix is designed for quick drainage and high aeration.

Exceptional Organic Matter Levels

Fertility is high here, with organic matter reaching 19.88%, which is nearly ten times the national average and well above the state average. An available water capacity of 0.145 in/in helps anchor this nutrient-rich environment for local flora.

Well-Drained Soil for Coastal Farming

Most of the county’s land is classified as well-drained, making it a reliable choice for diverse agricultural uses. This natural efficiency in moving water prevents the roots of most plants from becoming waterlogged in the coastal humidity.

A Haven for Salt-Tolerant Native Plants

Coastal zone 7b allows for a wide variety of plantings, especially salt-tolerant shrubs and native grasses. Start a garden this season to take advantage of some of the highest organic matter levels in the entire state.
