EXPERIMENT STATIOX BULLETINS

these beets at the factory is as follows, assuming that the factory pays $4.50 per 

 ton for 12 per cent beets and 33'/; cents per ton for each per cent above 12, the com- 

 putation will l)e like this. 



Marc, analu^'ous to the apple pomace left in making cider, is the insoluble material 

 left behind when all the soluble material is taken out and must be deducted from 

 the per Cfut of sugar in the juice to determine the per cent of sugar in the beet. Most 

 of the Mi< higan factories have fixed the marc at S per cent.

Thus, after removing the marc of 8 per cent, we find the actual sugar in the beets to 

 be 12.54 per cent. The 12 per cent is worth $4.50 and the .54X33i/3=$0.18+-.':;4.50=.i;4.(i8, 

 the price per ton. Therefore, the 14.08 tons per acre, at $4.68 per ton, are worth 

 $65.89. 



EXPERIMENTS ^YITH SUNDRY FERTILIZERS. 



Looking to solution of the problem of what is the practical value of our more 

 common fertilizing materials in their relation to the sugar beet crop, the following 

 experiment was begun in 1899. While the general table below gives us a plain 

 comparison of the effects of the several materials applied, it also supplies results which 

 may be n>fd in connection with the results secured from like treatments on other soils 

 and conditions. 



The soil was a medium loam, though not what would be considered strong land, 

 nor best adapted to the sugar beet crop. The fertilizers applied this year were prac- 

 tically the same in quantity and quality as were used the previous year. 



The results are showni in the table below:
