94 The Colorado Experiment Station 
tained on 22 June, 1910, 93.3 pounds of nitric nitrogen in the top 
four inches of the soil, the next lower section 106.2 pounds and the 
next lower 400 pounds, and this was all land in good cultivable con¬ 
dition. The beets on this date presented a good stand but were not 
particularly promising. I do not know the details of the cultivation 
received throughout the season. On 6 July there were applied to 
five rows, superphosphate at the rate of 1,000 pounds, to 5 rows 
potassic chlorid at the rate of 400 pounds, to 5 rows sodic chlorid at 
the rate of 400 pounds, to 5 rows superphosphate at the rate of 1,000 
pounds and potassic chlorid 400 pounds per acre, and to 5 rows 
superphosphate 1,000 pounds and sodic chlorid 400 pounds per acre. 
The fertilizers were applied by hand. I visited this field on 8 Aug. 
and the condition of the field was very promising. The foliage was 
exceedingly heavy, the petioles were erect, stout and long, the blades 
were large but did not vary more in shape than usual; they were 
thick and heavy in substance and very brittle. The hight of the 
leaves was about 36 inches, the color was from a dark to a bluish 
green. No difference could be detected between the rows to which 
the fertilizers had been applied and the rest of the field. The yield 
of the beets at this time promised to be very heavy indeed, the yield 
at harvest time was 11.7 tons and the sugar according to the factory 
returns was 14.14 percent. We took three sets of samples 23 Sept., 
11 Oct., and 3 Nov. The average weight of the beets was not de¬ 
termined except for the final, 3 Nov., samples. Owing to the num¬ 
ber of samples to be handled, only the plots to which the fertilizers 
were separately applied, a check plot and the very bad portion of the 
field—39 samples in all—were taken. The samples are numbered 
1, 2 and 3. Sample 1 is uniformly taken from the highest ground 
and corresponds to Sample III of the soil and 3 corresponds to Sam¬ 
ple I of the soil.
