New Jersey is a state located in the Northeastern United States.

It is bordered on the north and east by New York State, on the southeast and south by the Atlantic Ocean, on the west by Pennsylvania, and on the southwest by Delaware New Jersey is a leading agricultural state.

It ranks high in the production of blueberries and cranberries, bell peppers and peaches.

The below map shows the physiographic provinces of the state.

Now, we’ll understand with the help of a table.

Soil Order Of New Jersey

Northeastern Highlands1. These are typically cored by metamorphic crystalline rocks and forested
2. Uplands are characteristically are composed of Precambrian gneiss, whereas valleys are composed of much less resistant Paleozoic limestone and shale.
3. Gneissic soils are typically nutrient-poor, and clay- and iron-rich.
Middle Atlantic Coastal Plain1. Composed of Quarternary gravels, silt, and sands
2. Mostly dominated by wetlands
3. Swampy, marshy, and frequently flooded area
Northern Piedmont1. Alfisols are common
2. Soils are deep, well-developed, and have average to high base saturation.
3. Triassic brownish red, shale, sandstone, and argillite are extensive
Ridges and valleys1. Alfisols are common in limestone valleys
2. Inceptisols and Ultisols occur in shale valleys and on ridges cored by sandstone.
3. Valley soils are composed of limestone, shale, or glacial till and tend to be well-drained, well-suited for agriculture, and deeper and more fertile than ridge soils.
4. Ridge soils are stony, shallow, acidic, and not very fertile
Atlantic Coastal Pine Barrens1. are largely composed of quartz sand, are acidic, have limited nutrient availability.
2. These are Underlain by clays, silts, marls, sands, gravels, and shell beds.
