14 SOILS OF THE EASTERN UNITED STATES. 



western and northern regions where it occurs, and an increasing 

 occupation of this type for the purposes of dairying throughout its 

 extent. 



The most important suggestion which may be made for the im- 

 provement of the efficiency of the type is that of the adoption of crop 

 rotations suited to the climate of the different areas in which the 

 type is found. Some small portions of the type require supple- 

 mental tile drainage to complete the fair to excellent natural drain- 

 age of the soil and subsoil. 



The Carrington loam ranks high as a corn-producing soil and is 

 noted for the superior quality of the spring wheat grown upon it 

 in Minnesota and North Dakota. 



In regions of adequate rainfall, practically all of the Carrington 

 loam has been occupied for general farming purposes. In its more 

 western locations portions of the soil are still used for the cutting 

 of wild hay and for the grazing of cattle.
