It will be noticed that the amount of ash was greater 
in the beets raised on rich soil, while the amount of iron 
and alumina, calcium and phosphoric acid was the 
greatest in those raised on the poor soil. 
Of course, the farmer must return the mineral sub¬ 
stances used up by the beets and found in the ash, in 
order to obtain the best results in successive crops, and 
prevent impoverishing the soil. 
There may come some misunderstanding between 
the manufacturer and grower of sugar beets. It would 
be unfair to both, to buy and sell according to weight. A 
better way would be to take an average sample and have 
the juice extracted. An increased density, other things 
being equal, would indicate an increase of sugar. In 
many places it has been customary to take a specific 
gravity of 1.055 (7.27° Baume) as to the standard.
