FERTILIZER EXPERIMENTS WITH SUGAR BEETS. 5 
prevent freezing, and this also checked loss in weight from evapora¬ 
tion or drying out. 
In applying the fertilizer and manure a strip two feet wide was 
left between each two plats to which nothing was applied. The rows 
of beets which grew on these strips were measured and harvested 
separately,* weighed and counted. It will be seen that the average 
weight per beet in these rows between the plats is 0.7 of a pound less 
than the average weight given in Table 11 of the samples taken for analy¬ 
sis. While the estimated average tonnage per acre of these rejected 
rows is only 1.5 tons less than the actual average yields of all the plats. 
While no fertilizer was applied to the rows between the plats, practi¬ 
cally a great deal would be worked within reach of the roots from that 
applied on both sides. From this data it is fair to assume, that in 
spite of great care in selecting the samples the average weight of the 
beets chosen for analysis to represent the sugar content and purity 
of each plat is about one-third larger than the average weight per beet 
of all the beets harvested. Nearly the same proportion is found be¬ 
tween the twelve beets analyzed from Plat 6 and 366 beets dug for 
the same plat to note changes in maturing, reported in Table 17. 
However, the samples for analysis were selected in exactly the same 
way, so that the results were strictly comparable between themselves. 
This particular part of the data obtained shows that the 120 beets 
carefully selected to represent the whole field, were actually one 
third larger than 1,902 beets actually harvested.
