The Northeastern coastal forests are a temperate broadleaf and mixed forests ecoregion of the northeast and middle Atlantic region of the United States. The ecoregion covers an area of 34,630 sq miles (89,691 km2) encompassing the Piedmont and coastal plain of seven states, extending from coastal southwestern Maine, southeastern New Hampshire, eastern Massachusetts, and Rhode Island, southward through Connecticut, New York State, New Jersey, southeast Pennsylvania, Delaware and Maryland.
USDA soil taxonomy (ST) developed by the United States Department of Agriculture and the National Cooperative Soil Survey provides an elaborate classification of soil types according to several parameters and in several levels: Order, Suborder, Great Group, Subgroup, Family, and Series. The classification was originally developed by Guy Donald Smith, former director of the U.S. Department of Agriculture's soil survey investigations.
In USDA soil taxonomy, a Psamment is defined as an Entisol which consists basically of unconsolidated sand deposits, often found in shifting sand dunes but also in areas of very coarse-textured parent material subject to millions of years of weathering. This latter case is characteristic of the Guiana Highlands of northern South America. A Psamment has no distinct soil horizons, and must consist entirely of material of loamy sand or coarser in texture. In the World Reference Base for Soil Resources (WRB), Psamments are known as Arenosols.

In hillslope geomorphology, a rill is a shallow channel cut into soil by the erosive action of flowing surface water. Similar but smaller incised channels are known as microrills; larger incised channels are known as gullies.
Gordonia lasianthus is a small to medium-sized evergreen tree or shrub found in acidic, swampy soils of pinelands and bays on the Atlantic and Gulf Coastal Plains of the southeastern United States. It is a member of the tea or family Theaceae. It is slow growing with soft, light-colored, fine-grained wood of little commercial value, although loblolly-bay could be managed as a source of pulpwood. When older specimens are cut, the wood exudes a strong scent. It is similar to a mixture of fresh oranges and pine sap. The bark of the adult tree varies from medium grey to a red brown coloration. Dead adult specimens of loblolly bay exhibit a lustrous shine when exposed to sunlight for several years. The white showy flowers and shiny foliage make it a desirable ornamental, but it is not easy to cultivate. Deer browse stump sprouts heavily.
The Miami soil series is the state soil of Indiana.
The Appalachian–Blue Ridge forests are an ecoregion in the Temperate broadleaf and mixed forests Biome, in the Eastern United States. The ecoregion is located in the central and southern Appalachian Mountains, including the Ridge-and-Valley Appalachians and the Blue Ridge Mountains. It covers an area of about 61,500 square miles (159,000 km2) in: northeast Alabama and Georgia, northwest South Carolina, eastern Tennessee, western North Carolina, Virginia, Maryland, and central West Virginia and Pennsylvania; and small extensions into Kentucky, New Jersey, and New York.
Santa Rosa Creek is a 22-mile-long (35 km) stream in Sonoma County, California, which rises on Hood Mountain and discharges to the Laguna de Santa Rosa by way of the Santa Rosa Flood Control Channel. This article covers both the creek and the channel.
The Fairfield Osborn Preserve is a 450-acre nature reserve situated on the northwest flank of Sonoma Mountain in Sonoma County, California. There are eight plant communities within the property, oak woodland being the dominant type. Other communities include chaparral, Douglas fir woodland, native Bunch grass, freshwater marsh, vernal pool, pond and riparian woodland. The flora is extremely diverse including many native trees, shrubs, wildflowers, grasses, lichens and mosses. A diverse fauna inhabits this area including black-tailed deer, coyote, bobcat and an occasional mountain lion; moreover, there are abundant avifauna, amphibians, reptiles and insects.
Narragansett soils are loamy soils occurring in the northeastern United States. It is the state soil of Rhode Island.
Peaked Mountain is a nature reserve located in Monson, Massachusetts. The property is approximately 2,000 acres (8.1 km2) and is owned by The Trustees of Reservations, a non-profit conservation organization. The principal landowners of its western slope, Leonard and Roslyn Harrington and Richard Elliott, have long permitted the public to hike through their properties to the summit. Concerned about the mountain's future, they sought the assistance of The Trustees of Reservations in developing a long-term strategy for protecting the mountain and securing public access after their lifetimes.
Houdek is a type of soil composed of glacial till and decomposed organic matter. The soil series was established in 1955 in Spink County, South Dakota. It is unique to the United States, but in particular to South Dakota where it is the state soil.
In 1988, the Professional Soil Classifiers Association of Mississippi selected Natchez silt loam soil to represent the soil resources of the State. These soils exist on 171,559 acres of landscape in Mississippi.
Red soil is a type of soil that typically develops in warm, temperate, and humid climates and comprise approximately 13% of Earth's soils. It contains thin organic and organic-mineral layers of highly leached soil resting on a red layer of alluvium. Red soils contain large amounts of clay and are generally derived from the weathering of ancient crystalline and metamorphic rock. They are named after their rich red color, which can vary from reddish brown to reddish yellow as a result of their high iron content. Red soil can be good or poor growing soil depending on how it is managed. It is usually low in nutrients and humus and can be difficult to cultivate due to its low water holding capacity; however, the fertility of these soils can be optimized with liming and other farming techniques.
The Mississippi Alluvial Plain is a Level III ecoregion designated by the Environmental Protection Agency (EPA) in seven U.S. states, though predominantly in Arkansas, Louisiana, and Mississippi. It parallels the Mississippi River from the Midwestern United States to the Gulf of Mexico.
The soils of the Sa'isi Tsa'ida Imba woreda (district) in Tigray (Ethiopia) reflect its longstanding agricultural history, highly seasonal rainfall regime, relatively low temperatures, overall dominance of metamorphic and sandstone lithology and steep slopes.
The soils of the Tanqwa Abergele woreda (district) in Tigray (Ethiopia) reflect its longstanding agricultural history, highly seasonal rainfall regime, relatively high temperatures, overall dominance of Precambrian metamorphic rocks and steep slopes.
The Western Corn Belt Plains is a Level III ecoregion designated by the Environmental Protection Agency (EPA) in seven U.S. states, though predominantly in Iowa.
The Northeastern Highlands ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the U.S. states of Vermont, New Hampshire, Massachusetts, Maine, Connecticut, New York, New Jersey, and Pennsylvania. The ecoregion extends from the northern tip of Maine and runs south along the Appalachian Mountain Range into eastern Pennsylvania. Discontiguous sections are located among New York's Adirondack Mountains and the Catskill Range. The largest portion of the Northeastern Highlands ecoregion encompasses several sub mountain ranges including the Berkshires, Green Mountains, Taconic, and White Mountains.
