Deterioraiion Sugar Beets Due to Nitrates 63 
The effects of these fertilizers upon the weight of crocs the 
apparent coefficients of purity, and the amount of sugar produced 
have been given on page 19. These plots were harvested during

some of the plots. The samples from one of the plots, Number 24,

was harvested and the beets delivered to the factory 18 Oct. and 
averaged 15.35 percent sugar, apparent purity 84.45. Other plots 
also showed increases, but no other one to such an extent as number

two exceptions. ’ 
A set of eleven samples had already been taken 23 Sept The 
lesults obtained by determining the injurious nitrogen in these are. 
wi 1 one exception concordant in showing a great improvement in 
the quality of the beets. One sample shows a very surprising de- 
giee of improvement, but the determination of total nitrogen is 
apparently too low, which is mentioned in the tables. The following 
s a ement of the injurious nitrogenous compounds (injurious N x 
10) m the beets on 23 Sept, and 11 Oct. may serve to indicate the 
changes that took place in the beets during this interval.
