THE CABBINGTON CLAY LOAM. 9 



kraut and for local consumption. It is essential to have the soil 

 well drained and in good tilth for the profitable production of this 

 crop. The plants are set in the field between June 20 and July 10. 

 Heavy applications of stable manure are made and the soil thor- 

 oughly pulverized. The yields obtained range from 12 to 15 tons 

 per acre. 



Sugar beets are well suited to this soil and where the local market 

 is good are a profitable crop. The chief difficulty in the production 

 of this crop arises from the large amount of hand labor required 

 in the thinning, hoeing, and harvesting. 



Alfalfa has been successfully grown upon the better-drained areas 

 of the Carrington clay loam. The type is usually highly calcareous 

 in. the subsoil and its natural fertility is good. Where these advan- 

 tages are coupled with good drainage, alfalfa may well become a 

 very profitable crop for all of the areas lying within the more ele- 

 vated portions of the type. Poor drainage must be avoided if alfalfa 

 is to succeed. 



While the Carrington clay loam is suited to the production of 

 a fairly wide range of crops, the greatest success in its development 

 has been attained where a regular rotation has been adopted com- 

 prising corn as the intertilled crop, spring wheat or oats as the small 

 grain crop, and two or three years to grass production. When, in 

 addition, the crops grown are chiefly fed to live stock upon the 

 farm and the resulting stable manure is applied to the land, this 

 soil has maintained a high producing capacity. 



TARM EQUIPMENT. 



The farm equipment of the Carrington clay loam varies with the 

 class of agriculture which dominates the various areas where it 

 occurs. In the dairy and live-stock districts it comprises barns, silos, 

 and feeding sheds, while in the grain-raising regions it is more re- 

 stricted. In all cases the type is well equipped with buildings, work 

 stock, and machinery. Heavy draft animals are required for the 

 proper tillage of the soil and improved machinery is also generally 

 used. 



SUMMARY. 



The Carrington clay loam is an extensive general farming soil 

 chiefly developed in southern Wisconsin, north-central Iowa, southern 

 Minnesota, and eastern North Dakota. 



The surface of the type varies from nearly level to undulating and 

 gently rolling. Only limited areas are sloping or ridged. The natu- 

 ral surface drainage is good over the greater portion of the type. 

 Small depressions and sloughs are improved by the installation of 

 tile drains.
