Soil survey of Lee County, Iowa, L. V. Davis and M. E. Sar {U. S. Dept. 

 Ayr., Advance iShccts Field Operations Bur. Soils, 1914, PP- 36, pis. 2, fig. 1, 

 map 1). — This survey, made in cooperation with tlie Iowa Experiment Station 

 and issued March 10, 1916, deals with the soils of an area of 327,040 acres 

 in southeastern Iowa. 



"The county comprises two main physiographic divisions. The upland 

 plateau, with level to rolling topography, constitutes one division, and the 

 alluvial river terraces and first bottoms the other. The former occupies about 

 six-sevenths of the total area of the county." The soils of the county are of 

 loessial, glacial, residual, and alluvial origin. Nineteen soil types of nine 

 series are mapped, of which the Grundy silt loam, the Lindley loam, the 

 Putnam silt loam, and the Memphis silt loam cover respectively 27.5, 23.7, 

 11.4, and 10 per cent of the area. 



Soil survey of Cherokee County, Kansas, P. O. Wood and R. I. Theock- 

 MORTON {Kansas Sta. Bui. 207 {191.5), pp. 46, pi. 1). — This survey, made in co- 

 operation v,-ith the Bureau of Soils of this Department and noted in the Field 

 Operations of that Bureau for 1912 (E. S. R., 34, p. 322), deals with the 

 general characteristics, mechanical and chemical composition, and crop adapta- 

 bilities of the soils of an area of 374,400 acres in southeastern Kansas, consist- 

 ing mainly of residual prairie. 



The soils are residual upland soils and alluvial bottom soils. Including 

 meadow, 22 soil types of 13 series are mapped, of which the Bates silt loam 

 and the Cherokee silt loam cover 24.5 and 20 per cent of the area, respectively. 

 Chemical analyses of samples of the types are reported, the results of which 

 are taken to indicate that these soils are relatively deficient in nitrogen, phos- 

 phorus, potassium, and lime, and high in organic matter. The majority of the 

 soils are acid. 



A fertilizer test with wheat is included. 



Soil survey of Reno County, Kansas, W. T. Carter, Jr., et at.. (Kansas 

 Sta. Bui. 208 {1915), pp. 48, pi. 1). — This survey, made in cooperation with the 

 Bureau of Soils of this Department and noted in the Field Operations of that 

 Bureau for 1911 (E. S. R., 31, p. 513), deals with the general characteristics, 

 mechanical and chemical properties, and crop adaptabilities of the soils of an 

 area of 812,000 acres in south-central Kansas, the general topography of which 

 is that of a rolling plain intersected by three relatively narrow valleys. 



The soils of the area are upland and bottom soils and are formed (1) from 

 shales and sandstones, (2) from unconsolidated water-laid deposits, (3) from 

 a mixture of the above two groups, and (4) from wind-laid deposits. In- 

 cluding meadow and dune sand, 31 soil types of 10 series are recognized, of 

 which the Pratt loam and fine sandy loam and the Albion sandy loam cover 

 16.6, 15.1, and 11.1 per cent of the area, respectively. Chemical analyses of 

 representative samples of each type made at the station are reported, the re- 

 sults of which show that the nitrogen content averages 0.106 per cent for the 

 surface soil, 0.076 per cent for the subsurface soil, and 0.045 per cent for the 

 subsoil, and the phosphorus content averages 0.034 per cent for the surface and 

 subsurface soil and 0.031 per cent for the subsoil. The potash and lime con- 

 tents are considered to be relatively high, most of the soils containing more 

 than 2 per cent potassium. The average calcium content for the county was 

 0.88 per cent in the soil, 1.47 in the subsurface soil, and 1.73 in the subsoil.
