ground limestone. To plot 2 apply the same quantity of limestone and 

 inoculate the soil with alfalfa bacteria by spreading on it soil from an 

 old alfalfa field. This should be done in the late afternoon or on a

 lation. Plant the seeds and observe the results of the treatment as the 

 crop grows. Draw conclusions as to the best way to treat soil for 

 alfalfa in your region.
