Produktbeschreibung
Excerpt from Soils of the Eastern United States and Their Use XVII: The Porters Loam and Porters Black Loam The Porters loam and Porters black loam are two intimately associated types of soil which occur only at the higher elevations in the eastern ranges of the Appalachian system from Virginia southward through North Carolina into the extreme western portion of South Carolina, Although of limited geographical extent, these soils possess probably the greatest range in altitude of any types occurring east of the Rocky Mountains, since they extend from the low foothills along the eastern slope of the Blue Ridge Mountains to the extreme summits of the highest Appalachian peaks, covering the slopes and even the top of Mount Mitchell, at an altitude in excess of 6,700 feet. The Porters loam has been mapped in four different soil survey areas in the States of North Carolina and South Carolina to the total extent of 436,160 acres, while the Porters black loam has been encountered in seven areas in Virginia and North Carolina, and a total area of 193,550 acres has been included in these surveys. Characteristic Of Soil And Subsoil. The surface soil of the Porters loam to a depth ranging from 6 to 15 inches is a dark-brown, reddish-brown, or sometimes gray loam. The subsoil to a depth of 3 feet or more is a reddish-brown clay loam, immediately beneath the soil, but grades down into a heavier red clay at greater depths. Small fragments and masses of the parent rock are numerous in the subsoil, and are frequently found in the surface soil, although they only accumulate sufficiently to interfere with cultivation over small local areas. The Porters loam is readily distinguishable from all other soils of the eastern United States through the fact that it is the characteristic soil type of the mountain slopes of the western portions of both North Carolina and South Carolina. It lies at the higher altitudes over the foothills and flanks of the mountains and occupies even the crests of the foothills and lower ridges.
