SOIL SURVEY OF KIMBALL COUNTY, NEBRASKA. 



23 



The Scott silt loam, calcareous phase, is widely distributed in the 

 depressions which occur over the upland plains of the county, but is 

 found principally in the southern part. It occurs in separate small 

 bodies ranging from about 3 to 50 acres in extent, with one larger area 

 of about 1,000 acres Avest of Gifford. 



The soil material has been deposited in shallow basins and consists 

 of sediment from soils of the table-land. In places, owing to the 

 impervious nature of the subsoil, water accumulates in small ponds 

 after heavy rains and disappears very slowly, so that poor drainage 

 is prevalent over a large part of the phase. 



Only a very small part of this soil is under cultivation. It is more 

 difficult to plow the land and prepare a good seed bed than on the 

 associated soils of the Sidney series, but the topography is more 

 favorable to the retention of moisture. The areas support a thick 

 growth of native grasses, except in the areas of standing water. 



The following table gives the results of the mechanical analyses 

 of samples of the soil and subsoil of the Scott silt loam, calcareous 

 phase : 



Mechanical analyses of Scott silt loam, calcareous phase. 



TRIPP VEKY FINE SANDY LOAM. 



The surface soil of the Tripp very fine sandy loam consists of a 

 light-brown, very fine sandy loam, relatively high in the finest grade 

 of sand and in silt, and low in all the grades of material coarser than 

 fine sand. The soil is from 15 to 20 inches deep and is underlain by 

 gray or pale-yellowish material, differing only slightly in texture 

 from the surface material, though possibly containing a somewhat 

 higher percentage of silt. At a depth of 10 or 12 inches there is com- 

 monly in the soil a subsurface layer which is a little more compact 

 than the surface soil, but the material at 20 to 24 inches becomes dry, 

 mealy, and friable. The surface soil apparently is only moderately 

 calcareous, but the lime content increases with depth until the gray- 

 ish, highly calcareous subsoil is encountered, at a depth of 20 to 24 

 inches. 



This type is very similar in physical characteristics to the Chey- 

 enne very fine sandy loam, from which it differs chiefly in the greater 

 depth of the soil material over the gravelly substratum underlying all 

 the alluvial deposits of the county.
