Deterioration Sugar Beets Due to Nitrates 73 
There were three series of samples taken of these beets, 23 Sep¬ 
tember, 11 October and 3 November 1910. The third series was 
subjected to the fullest examination and is the most important, but 
the first two series will be given by themselves. They will enable 
us to obtain a better view of the development of the beet.

Some of these 
beets, 
Fields i 
and 2, show that the beets had 
improved some during the 18 days between the two samplings. The 
sugar and dry substances had increased, the proteid nitrogen had 
increased, while the total nitrogen had decreased. Fields 3, 4 and 5, 
however, which had received respectively 750, 1,000 and 1,250 
pounds of sodic nitrate per acre, showed no material improvement 
as measured by the percentage of injurious nitrogen in the beets on 
the respective dates.
