Produktbeschreibung
Excerpt from Soils of the Eastern United States and Their Use Vi: The Cecil Clay Even where excessive erosion has removed the surface soil material it requires only two or three years of careful tillage to redevelop a productive soil through the proper working of the stiff red clay subsoil. The recuperative powers of this soil after bad management and excessive erosion are remarkable. The Cecil clay constitutes the well-known "red lands" or "mulatto lands" of the Piedmont section. It is generally esteemed a strong productive soil for general farming purposes, and with proper treatment its value and reputation would be still further enhanced. The Cecil clay differs from the Cecil sandy loam in that the latter soil possesses a covering of the gray sandy loam over the stiff red clay subsoil. The soils of the Cecil series differ from all others of the Piedmont region, except those of the Penn series, through the persistent occurrence of the tenacious red clay subsoil under all the types of the series. The red soils of the Penn series are derived from sandstones and shales and thus may be distinguished easily from the Cecil soils, derived from crystalline rocks. Surface Features And Drainage. Areas of the Cecil clay are found at all elevations throughout the Piedmont sections. The lowest altitude at which it is reported is about 300 feet above sea level in some of the Virginia areas. It occurs in all intermediate elevations in the Piedmont section up to an altitude of 1,200 feet. It is usually found upon the hilly, rolling, or broken portions of the Piedmont section and in the more southern regions is strongly developed along the stream slopes and other eroded portions of the Piedmont Plateau. In the more northern regions through Virginia. Maryland, and in southern Pennsylvania it occupies undulating to rolling or hilly locations, and its sloping surface is only interrupted by the channels of the larger streams and by rocky areas where the residual bowlders still persist. Owing to its altitude and elevation, the drainage conditions over practically the entire extent of the Cecil clay are excellent. Only in rare cases is it necessary to practice any form of artificial drainage. In the more level fields it would frequently be advantageous to install some tile drainage systems, in order to carry off excess subsoil moisture. Excessive erosion is the greatest obstacle to the tillage of the Cecil clay. In fact, the type may almost be said to originate from erosion processes. Practically all of the rocks of the Piedmont section have been deeply weathered and the original rock masses broken down to form a complex mass of sand and clay.
