Soils and Topography
In North and South Carolina, loblolly-bay is apparently very soil-specific even though it is found on several soil series. It grows on certain Spodosols, Inceptisols, Ultisols, and Histosols and to a lesser degree on Entisols and Mollisols (7). Soil profiles of a loblolly-bay site in South Carolina have the following general characteristics at various soil horizons:
- A1- 0 to 25 cm (0 to 10 in) black to dark gray, fine sand, loamy fine sand or loamy sand, very strongly or extremely acid,
- A2- 25 to 38 cm (10 to 15 in ) black or gray, sand, loamy fine sand or sandy loam, very strongly or extremely acid (often there is no A2),
- B- 38 to 51 to 127 cm (15 to 20 to 50 in) gray or brown, sand to sandy loam, very strongly acid (often not present),
- C- 51 to 127 to 175 cm (20 to 50 to 69 in) gray or brown, sand, fine sand or loamy fine sand, strongly to very strongly acid.
Loblolly-bay grows in flat woodlands or shallow depressions with little or no slope, slow runoff, rapid permeability, and poor to very poor drainage. In South Carolina the soils are usually of sandy coastal plain or marine origin, except for the organic soils. The water table is at or near the soil surface for 6 to 9 months of the year.
In South Carolina's lower Coastal Plain, loblolly-bay is found in wet flats and in bays, typically the Carolina Bays (11). In the upper and middle Coastal Plain, it is found mainly along the edges of Carolina Bays and is widely dispersed in wet, flat woodlands on certain soil types.

Famous quotes containing the words soils and, soils and/or topography:
“He bends to the order of the seasons, the weather, the soils and crops, as the sails of a ship bend to the wind. He represents continuous hard labor, year in, year out, and small gains. He is a slow person, timed to Nature, and not to city watches. He takes the pace of seasons, plants and chemistry. Nature never hurries: atom by atom, little by little, she achieves her work.”
—Ralph Waldo Emerson (1803–1882)

“That the mere matter of a poem, for instance—its subject, its given incidents or situation; that the mere matter of a picture—the actual circumstances of an event, the actual topography of a landscape—should be nothing without the form, the spirit of the handling, that this form, this mode of handling, should become an end in itself, should penetrate every part of the matter;Mthis is what all art constantly strives after, and achieves in different degrees.”
—Walter Pater (1839–1894)
