PLOWING ALFALFA SOD. 423 



The growth seems to have exhausted the stored plant food, and 

 if the roots are all cut very little will start to grow, especially 

 if the field is planted to some crop like potatoes, that can be 

 well cultivated. Complaints about difficulties in plowing alfalfa 

 usually come from sections where rotation with alfalfa has not 

 been started long.
