In this experiment the increase of crop was not only considerable 

 on nearly all of the plots, but, considering both fodder and corn, 

 was especially large on those plots receiving the complete fertilizer. 

 This is in accordance with the general effect of nitrogenous manures 

 in increasing the proportion of straw or fodder to grain.
