We will briefly consider the classes of beets so far presented in 
regard to the nitrogen compounds present, their general character 
and some of the effects produced which may be attributed to the 
presence of nitrates whether added to or produced in the soil. We 
have sought to find good beets produced in Colorado and to deter¬ 
mine their composition. The beets grown in 1910 were evidently 
of medium quality, but much better in 1911, as indicated by the two 
samples given as representative of this year. The best Colorado 
samples taken in 1910 are from widely separated districts, Holly and 
Fort Collins, where the conditions were very dissimilar. The Holly 
sample was grown on newly broken sod land with a very moderate 
supply of water, a condition tending to lower the quality of the beets. 
We restate in the following table a few of the best samples:

These samples were all grown on good land, some with and 
others without fertilizers. Two of these samples were grown with 
the application of sodic nitrate, one with 250 pounds per acre, the 
other with 500 pounds, the latter in two portions. The first sample 
in the table was grown on new land, the other samples were grown 
on land which had been cultivated for years. The second sample 
represents the fifth consecutive crop of beets grown on the same land 
without fertilizers. The third and fourth samples were the second 
consecutive crop of beets on this soil. The first crop was not fer¬ 
tilized. This soil is well supplied with potash, 0.762 percent, also 
with phosphoric acid, 0.106 percent, and had an average supply of 
nitrogen for Colorado soils, o. 11 percent. The third, fourth and 
fifth samples were also the second consecutive crop of beets. The 
plot on which the fifth sample w r as grown received no fertilization of 
any kind either year. The soil in this case contained potash 0.95 
percent, 0.012 available, phosphoric acid 0.17 percent, 0.007 avail¬ 
able; total nitrogen, average of two samples done in duplicate,
