is to go to too little expense to accomplish a given result. These 

 investigations show that the largest net profits have usually been 

 obtained from crops raised by cultural methods involving a low cost 

 of production rather than from high yields obtained under methods 

 involving a high cost of production. Lessening the cost of production 

 -without proportionally lessening yields should therefore be given 

 first consideration. In other words, extensive rather than intensive 

 systems of farming should be followed. 



(7) Different types of soil and different combinations of climatic 

 conditions require different cultural methods and different combi- 

 nations of crops to produce the most profitable results. 



(8) The personality of the farmer and his family; the size, location, 

 soil, and environment of the farm; market facilities and prices; the 

 available capital, in cash, labor, or equipment, may any or all be 

 determining factors in the problem of profitable dry farming in the 

 Great Plains area. 



(9) Dry farming in the Great Plains area, in common with all 

 farming, to be successful must be systematized, and in order to 

 accomplish this, some definite rotation of crops should be established. 

 In planning such a rotation, due consideration should be given to all 

 the factors here enumerated, as they apply to each particular farm 

 and farmer. With these considerations clearly in mind, it is believed 

 that no intelligent farmer will experience any great difficulty in adopt- 

 ing a system of crop rotation and farm organization that will be better 

 adapted to his conditions than any that could be proposed by anyone 

 less familiar with these conditions than is the farmer himself.
