Excerpt from Soils of the Eastern United States and Their Use XXII: The Norfolk Sandy Loam The Norfolk sandy loam is an extensive soil type developed within the lower lying portions of the Atlantic and eastern Gulf Coastal Plains. It lies at varying altitudes from sea level up to 150 or 200 feet above tide, but the greater part of the type is probably found between altitudes of 50 and 150 feet. The surface of the Norfolk sandy loam is nearly level, undulating or gently rolling, and there are no steep Slopes or marked differences of elevation within the different areas of the type. The surface soil of the Norfolk sandy loam is a gray or a pale yellow medium sand, having a depth of about 12 inches. This is underlain to a depth of nearly 2 feet by a loamy sand or sandy loam of a yellow color which grades downward into a friable yellow sandy clay.

Excerpt from Soils of the Eastern United States and Their Use IV: The Sassafras Silt Loam It is apparent from the textural characteristics of the Sassafras silt loam, from its level to gently undulating surface topography, and from the classes of creps best suited for production upon this soil that the equipment required for its most economical tillage will dif fer very materially from the equipment to be used upon such other Coastal Plain soils as the Norfolk fine sand or Sandy loam, which are more easily worked and are not so universally planted to the general farm crops. The Sassafras silt loam should be plowed to a depth of 8 or 9 inches, and if the natural soil is not so deep as this the depth should be gradually increased from year to year.

Excerpt from Soils of the Eastern United States and Their Use X: The Marshall Silt Loam Not infrequently, however, there are found within the sub-soil concretions and accumulations of lime carbonate, and occasionally the limy remains of shells, principally of land forms of organic life. The Marshall silt loam is derived from the extensive body of fine silty rock powder which overspreads a considerable proportion of the central prairie States, mantling the older rock formations and covering the underlying glacial till to varying depths. This silty material doubtless originated from the outpouring of turbid water through the melting of the glacial ice during one of the later stages of its recession. It was widely distributed over the central portion of the Mississippi drainage region, and there is good evidence to show that when the surface of this material became dried and powdery it was taken up by the winds and thus distributed even over the higher elevations of that region hi the form of a thin mantle of loess. In fact the Marshall silt loam is one of several important soil types derived directly from the partial weathering of this loess mantle. It constitutes the brown prairie areas, stone free, and gently rolling to undulating in its characteristic surface features. The Marshall silt loam and other soils of the Marshall series are thus distinguished from the soils of the Miami series, which are light colored and derived from the weathering of the glacial till, and also from the black soils of the Carrington series, which resemble it in color, but have also been derived principally from ice-laid materials. It is separable from the soils of the Knox series, which also owe their origin to the surface layer of loess, in that the latter are distinguished by light-colored surface soils and are found within the timbered areas as contrasted with the prairie areas in which the darker Marshall soils occur. The black soils of the Waukesha series usually occur to the northward of the regions occupied by the Marshall silt loam and its associates, and the Waukesha soils are derived from the coarser outwash laid down directly by the action of moving water. The Marshall silt loam may be briefly characterized as the most important soil of that series, and as the brown to black silty prairie soil formed from the modification of the surface materials of the loess. Surface Features And Drainage. Throughout its entire extent the Marshall silt loam is marked by nearly level, slightly undulating, or gently rolling surface topography. Only where the larger streams have cut deep trenches are sloping areas found within this type. These, even, are infrequent since the eroded and sloping bluffs of the loess along the stream drainage ways are most frequently timbered and possess the lighter colored surface soils, thus falling within the Knox series as contrasted with the Marshall.
