About Soil in Passaic County, New Jersey

Intensely Acidic Northern Highlands

Passaic County features a very low average pH of 3.24, making it one of the most acidic regions in the state. This is far below the national median of 6.5 and even the New Jersey average of 4.24. Such low pH levels often require significant adjustment for standard garden vegetables.

A Light Mineral Framework

The mineral composition consists of 36.1% sand, 29.6% silt, and 9.4% clay. This low-clay mix prevents the soil from becoming heavy or compacted, even in the county's more rugged terrain. It provides an airy environment that is generally easy for plant roots to navigate.

The State's Richest Organic Soil

Passaic County boasts a massive 23.21% organic matter content, the highest among its neighbors and far above the 2.0% national average. This is paired with a superior available water capacity of 0.186 in/in. These soils are exceptional at storing water and nutrients, despite their high acidity.

High-Capacity Water Storage

While specific drainage classes are not provided, the high organic matter and 0.186 water capacity suggest a sponge-like quality to the land. This soil can absorb significant rainfall, which helps mitigate runoff in the county's hilly areas. Managing this moisture is key to successful local land use.

Abundant Potential in Zone 7a

With a 7a hardiness zone, Passaic County supports a versatile range of mid-Atlantic crops. The incredible organic matter levels provide a natural boost for any garden once the pH is balanced with lime. It is an ideal place to grow moisture-loving plants that thrive in rich, deep soils.
