of itself in the entire northern section. In the central

CONCLUSIONS 



As a result of the introduction of hardy adapted crops 

 and the increasing practice of crop rotation and diversi- 

 fied farming in conection with the production of regis- 

 tered and high grade live stock, the agriculture of South 

 Dakota is rapidly getting upon a permanent basis and 

 the prosperity of the state which depends entirely upon 

 its agriculture has constantly increased. The state is 

 growing rapidly in population. If a proper proportion 

 of this population interests itself in farming so that the 

 farm labor problem gradually becomes less acute, there 

 is every reason to hope for a continuation of this pros- 

 perity, due to increased farm production which can be 

 attained 1 by the better farm practice that will be possible 

 with more help available. 



In making these statements, we have tried to make it 

 clear that successful crop production in this state does 

 not depend upon any one minor practice, such as harrow- 

 ing the growing crop, harrowing fall plowing, excessively 

 deep plowing, packing or sub-soiling, but depends upon a 

 continuation and combination of all good farm practices 

 in connection with the use of good crop rotations and 

 good seed of adapted varieties with requisite attention 

 given to keeping up the fertility of the soil and improv- 

 ing its physical condition by the addition of barnyard 

 manure and the inclusion of clovers, alfalfas and similar 

 crops in the rotation system.
