SOIL SURVEY OF BAN^iER COUNTY, NEBRASKA. 



25 



pact, drab clay loam or clay, extending as a rule throughout the 

 3-foot section. The material is of lacustrine origin, having Ijeen de- 

 posited in shallow basins or depressions. The series is developed in 

 small areas throughout the uplands and is associated with the 

 residual types. Drainage is usually restricted, and in many areas 

 water stands on the surface part of the year. Both the soil and 

 subsoil are calcareous and soluble salts often accumulate in injurious 

 amounts. 



Dunesand includes areas of almost pure sand having a dunelike 

 topography and being subject to drifting. 



Eough broken land constitutes areas with a topography unsuited 

 to farming. 



The following table gives the actual and relative extent of the 

 several types of soil developed in Banner County. The distribution 

 of these soils is. shown on the map accompanying this report.

DUNLAP SILT LO.^il. 



The surface soil of the Dunlap silt loam is a dark-brown to brown 

 heavy silt loam. The silt content is unusually high and there is very 

 little sand of any grade. The soil is rich in organic matter and in 

 places where the topography has especially favored the accumulation 

 of this material the surface 6 inches is almost black. The soil is 

 slightly more compact than that of the Rosebud silt loam. 



The upper subsoil is a dark grayish brown, heavy, compact silt 



loam. At about 20 inches it passes into a gray or grayish-brown 



heavy silt loam to silty clay which typically continues throughout the 



3-foot section. In places the material changes rather abruptly at 



29367°— 21 4
