Nitrate of While no experiment comparing in equal quantities 



S r B t or g an i c Nitrate and ammonia Nitrogen, the general results 



so far favor the Nitrate. 



In the fertilizer experiment on page 130, the Nitrogen 

 in the commercial fertilizer analyzing 2.24 per cent ammo- 

 nia was undoubtedly of organic origin. The results from 

 three years' experiments show a yield of 20 per cent more 

 sugar from Nitrate Nitrogen than from the commercial 

 fertilizer containing dried blood or some other organic 

 Nitrogen. 



Nitrate Nitrogen vs. Ammonia Nitrogen. 



This experiment has been in progress for three years. 

 The results recorded on following page are from experi- 

 ments in three different fields of the College Farm. In 

 every case the potash and phosphoric acid applied on the 

 compared plots were identical. The quantity of Nitrate of 

 Soda and sulphate ammonia was in each case regulated 

 according to the ammonia content of the two materials, so 

 calculated that the same quantity of Nitrogen was applied 

 in every case where results are compared. 



The following is a fair comparison of Nitrate of Soda 

 and sulphate ammonia as a source of Nitrogen for sugar- 

 beets, and being the average result from five different 

 experiments conducted for three years in succession, and 

 showing a yield of over 1 1 per cent more sugar from the 

 Nitrate than from the ammonia presents conclusive evidence 

 of the superiority of the former.
