EXPERIMENT STATION RECORD. 



benefit resulting from such a practice must be ascribed to the activity 

 of the micro-organisms with which the soil is inoculated. In addition 

 to nitrified soil or nitrate of soda, both applied at the rate of 200 kg. 

 per hectare, a general application of 20,000 kg. of barnyard manure per 

 hectare was given. The following table shows the results obtained :

In 1897 the work was continued along the same lines. Unlike the 

 fall of 1896, the fall of 1897 was comparatively dry. The following table 

 presents the difference in composition of the beets for the two seasons : 



Comparison of the composition of beets grown in 1896 and 1897. 



The A^ilmorin sugar beet varied least in composition. The Tankards 

 were found to contain a large percentage of nitrate of potash and are 

 considered of little value on this account. This season nitrified soil 

 was less effective than nitrate of soda for all varieties. 



A comparison of varieties of sugar beets grown this season is shown 

 in the following table :
