SPRING WHEAT IN THE GREAT PLAINS AEEA.

fixed cost per acre ends, which, as before stated, is when the 

 grain is in the shock. Knowing that the average farm value of wheat 

 in the granary is 80 cents per bushel, and that it costs 10 cents per 

 bushel to take it from the shock, thrash it, and put it in the granary, 

 it is obvious that it would be worth 70 cents per bushel in the shock. 

 This valuation of 70 cents per bushel has therefore been used as a 

 basis for calculating the relative crop values, costs, and profits per 

 acre of these various methods. 



In conformity with the foregoing explanation, Table IV gives in 

 detail the cost of producing wheat in the shock, expressed in dollars 

 and cents, and in bushels per acre at 70 cents per bushel in the shock.

RESULTS AT THE SEVERAL STATIONS. 



Accompanying the presentation of the results for each station is a 

 brief soil description, with particular reference to the depth of the 

 soil and its water-holding capacity. Only such information is given 

 as is necessary to understand fully the interpretation of the results. 



JUDITH BASIN FIELD STATION. 



The field station at Moccasin, Mont., in the Judith Basin, is located 

 on a heavy clay soil of limestone origin. The soil is apparently very 

 rich in available fertility. It is underlain, at a depth of approxi- 

 mately 3 feet, by a limestone gravel that is closely cemented with 

 lime materials. The gravel subsoil, which extends to a depth of 

 about 30 feet, is practically free from soil. While it is so closely 

 cemented that it does not unduly drain the soil, it is not of a character 

 that allows the storage of available water or the development of 

 roots within it. The presence of gravel in the surface soil does not
