(SOIL SURVEY OP KIMBALL COUNTY, NEBRASKA, 25 



CHEYENNE FINE SANDY LOAM. 



The surface soil of the Cheyenne fine sandy loam typically is a 

 light-brown or grayish, loose fine sandy loam, about 10 to 15 inches 

 in depth. The subsoil is characteristically lighter in color than the 

 surface material, and coarser in texture, containing a high percentage 

 of gravel either within the 3-foot section or in the immediate sub- 

 stratum. In the deeper phases there is commonly a light-gray, 

 highly calcareous layer betw^een the surface soil and the underlying 

 gravel bed. 



The type occurs as narrow, irregular patches on the alluvial ter- 

 race, or bench land, lying 10 to 40 feet above Lodgepole Creek, and 

 is also found on the level valley floors of the larger draws, w^here it 

 is 3 to 10 feet above the drainage channels. The surface is nearly 

 level or slightly undulating, but is dissected by the meandering 

 stream channels and tributary draws. 



The type is of small extent and of minor agricultural importance. 

 The land is droughty when farmed under dry-land methods and has 

 too free underdrainage, especially in the shallow areas, to be success- 

 fully irrigated. 



The soil does not support as thick a growth of grasses as the 

 heavier types, and it has a lower grazing value. There is a smaller 

 proportion of grama and buffalo grasses than on the loam and silt 

 loam soils of the upland. The creeping prickly-pear cactus of this 

 region seems to show a preference for this and similar dry sandy 

 types. 



CHEYENNE VEBY FINE SANDY LOAM. 



The soil of the Cheyenne very fine sandy loam consists of a light- 

 brown or brown very fine sandy loam about 15 to 20 inches in depth. 

 This grades rather abruptly into a light-gray, very fine sandy loam 

 or silt loam, having a mealy, friable structure, and this in turn rests 

 upon a bed of coarse sand and gravel at depths of 3 to 4 feet. The 

 color indicates a fair content of organic matter to a depth of 10 to 12 

 inches, where the material becomes lighter in color and increasingly 

 calcareous. 



This type is confined to the valley of Lodgepole Creek, in which 

 it occupies alluvial terraces lying 15 to 40 feet above the creek level. 



The topography is nearly level or gently sloping. The land is 

 well drained, and the surface is favorable for irrigation. The porous 

 character of the subsoil permits free underdrainage. 



The greater part of the type is under cultivation. Alfalfa, Irish 

 potatoes, and sugar beets are the principal crops grown under irri- 

 gation. The yields are about the same as, or slightly lower than, 

 those obtained on the Tripp very fine sandy loam, in which the 

 porous gravelly substratum lies at greater depths. Under dry-land
