Deterioration Sugar Beets Due to Nitrates 69 
and poor beets falls, so far as the injurious nitrogen per 100 of 
sugar is concerned. In other articles he apparently considers an 
amount of injurious nitrogen larger than 0.370 as objectionable as 
beets grown without the application of fertilizers contain as little as 
0.280 injurious nitrogen per 100 sugar and when this was raised to 
0.3/0 by the application of fertilizers he considered their influence 
deleterious. I therefore infer that we are safe in considering a beet 
carrying more than 0.450 injurious nitrogen per 100 of sugar as 
doubtful 111 quality and 0.9 or more as decidedly poor. 
We will state these data in tabular form for the Colorado sam- 
pies previously discussed.

f considering the quality of these beets it is to be remembered 
1 lat the injuiious nitrogen is only one of the three criteria whereby 
we are to judge, the other two are the percentage of the sugar and 
the amount of injurious ash. Of these beets number VIII is the 
only one grown in 1910 that carries more than 15.3 percent sugar 
and less than 3.0 parts injurious ash per 100 of sugar, so while it is 
inferior to some of the other beets in respect to the injurious nitro¬ 
gen contained, it is one of the best beets in the list. Of the remain¬ 
ing twenty samples, sixteen are from the Arkansas Valley and four 
irom the College Experiment Farm at Fort Collins, two grown in 
1910, which are decidedly poor beets, having one good quality in a 
moderate degree and two samples grown in 1911 which are of good 
qualiry. All of the Ai Kansas Valley samples were grown in 1910 
and some of them are excellent beets, but some of them are very bad 
beets, for instance Number XX which had 12.7 percent sugar, 
01 3669 percent injurious nitrogen in the fresh beet or 1.073 parts
