Sugar
The ground is tilled in an indifferent fashion and no fertilizing
whatever is done. When virgin soil is planted, the seed is put in at
seven-foot intervals, sometimes greater, without any holes or furrows
having been made; the cuttings are simply stuck in the ground and partly
covered with earth. The cane ripens in fourteen months or more. Ratooning
follows until the yield gets so small that replanting is necessary. When
this time comes, the old roots are ploughed up and furrows from four
to six inches in depth are made about five or six feet apart. The seed
cane is planted in these furrows at four- or five-foot intervals. The
yield from virgin soil is very heavy and has been known to reach ninety
tons to the acre, but the sugar content of such crops is low, whereas
the subsequent ratoons with a decreased tonnage of cane per acre give
juice of a better quality. A fair average production on a plantation
having 4000 acres in cane would be about twenty-four tons to the acre.
Naturally this estimate would be affected by the relative proportions of
plant cane and ratoons, as well as by the character of the soil. Planting
is generally done in June and October, while the harvesting begins in
December and continues until April.
Manufacturing methods in Santo Domingo admit of much improvement. Single
crushing is the method employed for the most part, so that the loss in
extraction is considerable. The juices are treated and the suspended
impurities allowed to settle at the bottom of the tanks. Filter presses
are the exception rather than the rule, and for want of them the sugar
in the resultant mud is lost. The clear juices are then concentrated and
boiled to grain in vacuum pans. First sugars generally polarize between
95 degrees and 97 degrees, seconds about 86 degrees. The molasses is
either made into rum or permitted to run to waste. Notwithstanding the
crude character of the factories and machinery, the recovery of sugar is
generally good, the average being between 9 per cent and 11 per cent of
the weight of the cane, with single crushing.
Almost all of the factories are managed by Americans, but, as has been
said, the equipment they have to work with is by no means modern, and
under the extremely uncertain political conditions that prevail there is
scant encouragement for outside capital to come in and improve matters.
Just when a change for the better will come is impossible to say.
