1 he beets grown on unobjectionable land may be either good or 
ver y pool iu quality, often as poor as the sample given in the last 
column but, of course, this is not always the case. The sample 
gi\ en in the third column is probably a fair average of the beets of 
this class. 
Colorado soils produce under favorable conditions most excel¬ 
lent beets, though it seems probable that even under the best condi¬ 
tions our beets contain a rather large amount of ash, specifically of 
injurious ash. Notwithstanding this fact many of our beets during 
the past seven or eight years have been very low in quality. The 
cause for this fact is indicated by the high percentage of nitrogen 
present in the form of nitrates. 
^ le secon d class of beets, i. e., such as were grown with fer¬ 
tilizers to determine their effects, was also a disappointment. The 
effects of fertilizers, stockyard manure, phosphoric acid, potash and 
nitrogen, upon the yield and sugar content of the beets proved to be 
disappointing in that no single fertilizer or combination of fertilizers 
improved either the yield or percentage of sugar so positively as to 
force our consent to it as a fact. The results in regard to their 
effects upon the quality of the beets are uniformly unfavorable, some¬ 
times a favorable feature may be recognized, but this is more than 
counterbalanced by others which are unfavorable. There were 
eleven samples of these beets fully analyzed except that the press 
juice was not investigated. There were two check samples and 
nine samples grown with various fertilizers. The best results were 
obtained with the samples from one of the check plots and from the 
two plots which had separately received 300 pounds of potassic sul¬ 
fate and 400 pounds of superphosphate per acre. The total nitro¬ 
gen in the beets from these plots was low, 0.10875, 0.1232 and 
aT28 95 pei cent, the nitric nitrogen was low in the sample from the 
plot that received the potassic sulfate, but not especially low in the 
others, 0.01034 and 0.00967 percent. The pure ash in the beets 
from these plots was uniformly high; about 1.00 percent, the phos¬ 
phoric acid in the pure ash was uniformly low, but owing to the 
Troteids determined by Stutzer’s method.
