Lime: — On at least two of the fields the lime was absolutely essential 

 to success and on ten fields it was shown to be beneficial in promoting a 

 strong vigorous growth. In a number of cases the lime appeared to be 

 of no value when applied alone, but when inoculated soil was used in 

 connection with it, an excellent growth was secured.

Inoculation: — These tests unquestionably indicate the value and need 

 of inoculating the soil before seeding alfalfa. On nine of the fields the 

 reports indicate that inoculation was absolutely essential to the best 

 results though in many cases some other treatment was also necessary. 

 This was most often manure, though on a number of soils which were 

 undoubtedly acid, an application of lime was also necessary before the 

 inoculation was effective.

FIELDS INFLUEJN'CED BY TREATMENT 



In reporting to the Experiment Station the first cutting in 1911 the 

 co-operators were asked to estimate the comparative yields of field cured 

 hay on the portions receiving the different treatments basing their com- 

 parisons on an assumed yield of 1.5 tons per acre on the untreated plots. 

 From table XV it will be seen that on this basis the lime increased the 

 yield of the first cutting nearly .5 ton; the bone meal .64 of a ton; in- 

 oculation .83 of a ton, and manure 1.03 tons.
