On_Onslow loamy fine sandOn-Onslow loamy fine sand.
This nearly level, moderately well drained and somewhat poorly drained soil is on broad smooth flats on
the uplands. Areas are irregular in shape and small in size. Most of the acreage is used as residential and
industrial sites. The rest is forested (figure 3, at end of section). The dominant native vegetation is longleaf
pine, loblolly pine, oaks, holly, hickory, dogwood, blackgum, waxmyrtle, sweet pepperbush, gallberry, and
huckleberry.
Typically, the surface layer is gray loamy fine sand 7 inches thick. The subsurface layer is 10 inches thick.
It is mottled dark brown and yellowish brown loamy sand in the upper part and mottled light yellowish
brown loamy fine sand in the lower part. The subsoil is 47 inches thick. It is mottled light yellowish brown
sandy clay loam in the upper part, mottled pale brown sandy loam in the middle part, and light gray clay
loam in the lower part.
Included with this soil in mapping are small areas of Norfolk, Lynchburg, and Seagate soils.
The organic-matter content of the surface layer is low. Permeability is moderate, available water capacity
is medium, and shrink-swell potential is low. Reaction is very strongly acid or strongly acid throughout
where this soil is not limed. The seasonal high water table is at a depth of about 2 feet.
A seasonal high water table and moderate permeability are the main limitations in the use and
management of this soil. This soil is well suited to all locally grown crops. The main crops are corn,
soybeans, peanuts, and tobacco. Winter cover crops, minimum tillage, and crop residue management aid
in maintaining organic-matter content. This soil has good tilth and can be worked over a fairly wide range
of moisture content, but tillage is delayed during wet seasons. Some crops, such as tobacco, require
drainage. Most lawn grasses, shrubs, and trees are fairly easily established and maintained. Capability
