Nitrate Nitrogen vs. Ammonia Nitrogen. 



This experiment has been in progress for three years. 

 The results recorded in the following table 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 ex- 

 periments 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 evi- 

 dence of the superiority of the former. 



In Germany and France, where beet sugar raising is 

 much more largely and successfully carried on than in this 

 country, the benefit of using Nitrate of Soda is thoroughly 

 understood and is one of the reasons why sugar beet grow- 

 ing is conducted with greater success than in this country. 



The principal points to be remembered when using 

 Nitrate on sugar beets are : 



First — The Nitrate should be applied ^^r/v— either be- 

 fore or shortly after the beets come up — and the quantity
