injurious nitrogen equal to 10.73 parts injurious nitrogenous mat¬ 
ter per 100 parts of sugar. 
I believe that the table faithfully represents the characteristics 
of the Arkansas Valley beets—i. e., low sugar, as a rule, low total 
nitrogen, a low ratio for the proteid nitrogen, a high content of in¬ 
jurious nitrogen, and a liberal amount of injurious ash. Our ex¬ 
periments with fertilizers do not give us much, if any, reason for 
expecting to either profitably increase the quantity or quality of 0111 
crops by their use. This is the important feature of our experi¬ 
ments. We may not be able to give a satisfactory explanation of 
the fact, but this is the finding of several independent experimenters. 
The only fertilizers claimed by any one to have produced good re¬ 
sults are farmyard manure and nitrate of soda. I think that there 
is a general agreement in regard to the former but not in regard to 
the latter. It is altogether probable that favorable results have been 
obtaind by the use of sodic nitrate but this does not seem to have 
been the general result. The few favorable results obtained were 
probably due to conditions, which if known, were not mentioned. 
In the series of experiments given phosphoric acid and potash were 
combined with the nitrate, in the hope that we might obtain the good 
effects of the nitrate and neutralize its known bad effects. Our re¬ 
sults have been given in detail and they are indifferent both in crop 
and quality The conviction has prevailed for a long time that sodic 
nitrate exercises an injurious action on the quality of the sugar 
beet, but this has been questioned as we will see later. 
Up to the present, I have aimed to give beets grown under 
favorable conditions so that we might learn as far as possible what 
is a good crop and a good quality of beet with us. I think that the 
beets grown on the prairie land in the Arkansas Valley and. the 
beets grown near Fort Collins in 1910 and also those grown on the 
-College Farm in 1911 are good beets, the last being the best. They 
were "taken 11 Oct. and showed 23.0 percent of dry matter, 15.8 
percent sugar, 2.37 parts injurious ash and 3.85 of injurious nitro¬ 
genous matter per 100 sugar. But 1911 seems to have been an ex¬ 
tremely favorable year. In 1910 the samples from the Arkansas 
Valley, taken 23 Sept, were also good though grown under some- 
what adverse conditions. Dry matter 20.2, sugar 14.2, injurious 
ash 3.5 parts per 100 sugar and injurious nitrogenous matter 3.74 
parts per 100 sugar. Our adopted standard grown in 1910 near 
Fort Collins gave us dry matter 24.2, sugar 18.3, injurious ash 2.197 
parts per 100 sugar, injurious nitrogenous matter 6.29 parts per 100 
sugar. Analyses XVIII, XIX and XX of beets grown under 
favorable conditions are indifferent or bad in quality, especially XX, 
which gave us dry matter 20.0, sugar 12.7, injurious ash per 100 
sugar 3.7, injurious nitrogenous matter per 100 sugar 10.72 parts.
