78 The Colorado Experiment Station 
The samples already presented represent three classes of beets, 
all grown upon supposedly good ground. The first class was grown 
without fertilization of any sort. It is not hereby intimated that 
they are, because of this fact, to be considered as good beets. The 
second class was grown with application of various fertilizers to see 
if any combination used would materially improve the quantity and 
quality of the crop. In this place the quality alone is considered, 
the crop has already been stated. The third class was grown with 
the application of different quantities of sodic nitrate to determine 
what its effect upon the quality of the crop may be. The land 
chosen was the best available. The results obtained with the beets 
grown on the check plot in this case differed so little from those 
obtained with the application 'of nitrates that a sample was taken 
from an adjacent field, but this proved to be one of the poorest sam¬ 
ples of all. 
As we have given the nitrogen compounds precedence over the 
injurious ash, we will bring together the results obtained so far and 
it will make plain how the results stand. For this purpose we will 
give the total nitrogen, the nitric nitrogen, the injurious nitrogen in 
the beet and the injurious nitrogen per 100 parts of sugar.
