idea of the relative merits of these latter fertilizers in comparison with those in 

 the former portion of the experiment. 



The wood ashes contained 1.95% potash and 1.46% phosphoric acid. Home mixed 

 fertilizer was made up of three hundred pounds dissolved phosphate rock, fifty pounds 

 nitrate of soda, fifty pounds of sulphate of ammonia and one hundred pounds of sul- 

 phate of potash (plot 21).

Throughout the period of growth there was a slightly gi'eater development of leaf 

 oil the plots receiving lime than those uuder similar treatment, though uulimed; 

 while to the credit of nitrate of soda was earlier germination and a decidedly greater 

 development of the plants all thi'ough the first half of the season. 



Attention is called in the following table to the effect of nitrate of soda as com- 

 I)ared with sulpliate of ammonia, as a fertilizer for sugar beets:
