Deterioration Sugar Beets Due to Nitrates 89 
genous substances, by multiplying it by 10—the factor 16.1 has also 
been suggested, we will use the lower factor—when we obtain for 
the two analyses in the order given, 11.96 and 10.72—amounts 
which are more than twice that which justifies us in classifying the 
beets as of poor quality. The sugar in these two samples of beets 
was 14.2 and 12.7 percent respectively and the injurious ash per 
100 of sugar was, in LXXIX, 3.104 and in XX, 3.703 parts. As 
previously stated I have been unable to find a definite statement re¬ 
garding the permissible amount of injurious ash in a beet. Of 
course a beet would not be judged by the amount of injurious ash 
alone, other factors are also to be taken into consideration. We do, 
however, find that Andrlik mentions the increase in the injurious 
ash from 1.45 to 1.89 parts or 0.44 part, in connection with an in¬ 
crease of 0.38 part of injurious nitrogen and a depression of 1.2 
percent, from 17.8 to 16.4, in the sugar content as a very unfavor¬ 
able action upon the quality of the beet. Again in the analyses of 
cossettes quoted from another article of Andrlik’s, we find in 
Analysis VI which he says is a good beet, 1.947 parts injurious ash 
per 100 sugar and in V which he classifies as a poor beet, we find 
2.759 parts, so in considering the injurious ash in our beets we may 
tentatively assume that 2.0 parts injurious ash per 100 of sugar in 
the beet is a reasonable limit for the permissible amount of injurious 
ash in an otherwise fairly good beet. Judged by this assumed 
standard our nitrate beets are quite bad, reaching a maximum quan¬ 
tity of 5.472 parts injurious ash per 100 of sugar—and our beets in 
general so far as they have been presented are indifferent or de¬ 
cidedly bad. We have presented but two samples and they were not 
from Colorado, in which the injurious ash is below 2.00 parts per 
100 of sugar, and these have 1.67 and 1.9447 parts. Our best beets 
grown at Fort Collins approximate it with 2.2, 2.4 and 2.4 parts, 
but other Fort Collins beets are higher, 3.4 parts. The beets grown 
with the application of fertilizers are, in this respect, decidedly lower 
in quality as they show from 4.3 to 7.7 parts injurious ash per 100 
of sugar. I have already called attention to the amount of chlorin 
in the ashes of these samples. In several of the analyses given the 
sodic chlorid amounts to 30 or even more percent of the pure ash 
and a still larger percentage of the injurious ash. 
We have given the injurious nitrogen in Analyses LXXIX and 
XX. Analysis LXXIX is a sample of beets taken from the plot 
that had received 1,000 pounds of nitrate per acre in four equal 
applications. We find that the injurious introgen amounts to 1.403 
parts per 100 of sugar. This sample shows the largest amount of 
nitric nitrogen of any of the samples taken from these fields and it 
amounts to 0.566 parts per 100 of sugar. More than one-third of 
the injurious nitrogen in this sample was present as nitric acid re-
