inoculation of alfalfa is probably advisable even for 

 prairie soils when it is uncertain whether either the me- 

 lilotus or alfalfa genus are present in great numbers. 



In regions in Alabama where neither alfalfa, melilo- 

 tus, nor bur clover is extensively grown, inoculation of 

 alfalfa is advisable. Foi-^this purpose one may use soil 

 from old fields of either of 'these plants or inoculating 

 material prepared in the laboratory.
