Sugar Beets. 
19 
There is a little more dry matter in the top one third of the 
beet than in the other two thirds. 
Stock beets contain less dry matter than sugar beets. We 
found the dry matter ranging from 12.25 to 14.63 per cent, in 
mature beets. 
The marc or pulp, the portion left after the sugar and soluble 
matters have been washed out, ranged from 4.21 to 5.25 per cent. 
The average is about five per cent. 
For fodder analyses of sugar beets grown on alkali soil and soil 
free from alkali, of stock beets, beet tops, and marc or pulp, see 
bulletin No. 46, page 37. 
Alkali in the soil tends to increase the percentages of ash and 
albuminoids. 
The feeding value of dry pulp may safely be estimated as 
equal, pound for pound, to the dry sugar beet. 
One ton of sugar beets yields about four hundred pounds of dry 
matter, and only one hundred pounds of dry pulp. One ton of 
stock beets yields about two hundred and forty pounds of dry 
matter, which is richer in albuminoids and nitrogen-free extract 
than the pulp is; the pulp, however, is a by-product and the stock 
beets are not. 
The percentage of crude fiber in beets is quite irregular, but 
uniformly higher in beets from alkalized ground than others. 
Alkali affects the composition of the beets more than that of 
the leaves. 
The percentage of ash in the beet ranged from 0.79 to 1.33 per 
cent, in immature beets, samples harvested September 2nd, to from 
0.95 to 1.39 per cent, in mature beets harvested October 13th. The 
average is 1.10 per cent, of ash in the fresh beet. 
Fifty-eight per cent, of the total ash constituents removed from 
the soil by tne roots, and 70 per cent, of all the mineral constituents 
removed by the leaves, had been gathered by September 2nd. The 
accumulation of ash constituents continues until the period of 
ripening. 
The slight decrease in the percentage of ash as the roots ap¬ 
proach maturity is due to the rapid increase in the weight of the 
beets. There is no diminution in the amount of ash constituents 
in the crop. 
The influence of alkali, present in large quantities, is to in¬ 
crease the ash by about two per cent., reckoned on the dry matter.
