HC&S
cultivates over 37,000 acres of sugarcane, harvesting about half each
year. HC&S produces over 200,000 tons of raw sugar and more than
70,000 tons of molasses annually.
AG OPERATIONS
Land Preparation - Fields receive 2 to 4 passes by a 36-inch
harrow implement to break up the soil and facilitate water movement.
Caterpillar D-8s, with 3 ripper shanks, then rip the subsoil.
Seed Production - Although sugarcane flowers can produce a true
seed, cane is normally propagated by vegetative cuttings. At about 8-9
months of age, cane stalks are mechanically cut into 12 inch sections.
Each seed piece has 2-3 nodes from which new plants will grow. These
cuttings are dipped into 125 degree water for 30 minutes (for smut control)
and then into a cold water fungicide solution for 1 minute to prevent
fungus rot of the seed.
Planting and Ratooning - Cane is planted in twin lines with a
spacing of 3 feet between the two lines in each pair and 6 feet between
each pair of lines. Specially designed planting machines make furrows,
inject drip irrigation tubing into the soil, and drop in seed pieces.
Any gaps in the seed line are filled in by a follow-up crew before the
furrows are covered over by a standard farm tractor.
A few weeks after harvesting, the remaining cane stumps send out new
shoots (ratoons). These shoots are cultivated for the second and subsequent
crops. Before the ratoons emerge, however, areas of compacted soil are
plowed. Then, after the shoots are visible, the drip tubing is re-injected
and seed is placed in any blank spaces of the cane line by a replanting
unit fabricated on a D-6 undercarriage.
Irrigation - Growing of sugarcane on Maui is highly dependent
upon irrigation. One of the important projects of the founders of the
plantation was the building of the irrigation system which brings East
Maui mountain runoff water to the arid central valley of Maui. East
Maui Irrigation Company, a subsidiary of Alexander & Baldwin, Inc.,
owns and operates this water collection and delivery system. It consists
of over 74 miles of ditches and tunnels and has the capacity to deliver
approximately 450 million gallons of mountain water per day to HC&S.
The Waihee ditch system in West Maui is jointly owned and operated by
HC&S and Wailuku Agribusiness. This system has 12 miles of ditches and
tunnels and can deliver 120 million gallons per day to HC&S. In addition,
HC&S maintains 42 miles of main supply ditches and 47 reservoirs on
the plantation. The reservoir storage capacity is 1.065 billion gallons.
In addition to surface runoff water, HC&S has sixteen deep well pumping
stations that can deliver an additional 242 million gallons per day
of brackish ground water to the lower elevation fields. During an average
year, approximately 55% of the water comes from surface runoff sources
and the balance from the wells.
Efficient drip irrigation systems supply water to all of the cultivated
area of the plantation. The drip systems use thin-wall polyethylene
tubing to apply water. Each tube serves two adjacent rows of sugarcane.
Fertilizer is applied through the irrigation system. From 290 to 340
pounds of nitrogen are applied per acre during the first year of the
crop. Phosphorous and potassium are applied as determined by soil and
plant analysis. In addition, calcium carbonate and calcium silicate
may be applied by the broadest method at planting time, depending on
soil analysis.
Pest Control - Insect pests are controlled with biological methods-
"bugs eating bugs". Most diseases are controlled through the development
of resistant varieties.
Weeds are probably the biggest economic pests to sugar cane culture.
The current practice on weed control is an initial pre-emergence application
of Pendimethalin, Diuron, Ametryn, and/or Atrazine in various combinations.
One or two subsequent applications of Ametryn-Atrazine-Diuron-Velpar
combinations are applied by tractor or knapsack as needed. Also, noxious
weeds are controlled by applications of Round-Up in specific problem
areas.
Harvesting - At two years of age, the sugarcane is ready for
harvesting. First, the field is burned to reduce the amount leafy matter,
tops, dead cane, etc. going to the factory. Large push rakes (Caterpillar
D-8s) push the cane into long windrows. Hydraulic cranes with a 4 ton
grab capacity load cane into haulers. Each of our 18 haulers is capable
of carrying 45-65 tons per load. Harvesting is done on a continuous
schedule, operating seven days a week, to maximize factory utilization.

FACTORIES - The Puunene Mill, built
in 1901, has been repeatedly modernized and has a rated capacity to
process 7,200 tons of cane per day. The mill was among the first in
the industry to be completely computer controlled. The mill grinding
season is approximately 190 working days. A four to six week year-end
period is used for maintenance and repair of equipment in the mills.
POWER - HC&S
generates its own electric power, primarily from renewable sources,
in two steam and three hydroelectric plants. The primary fuel used in
the steam plants is bagasse, the fiber residue of the cane plant. HC&S
turns about 500,000 tons of bagasse into power annually. The electricity
produced meets all the plantation's power requirements. HC&S sells excess
electricity to Maui Electric Company, meeting about 10% of the power
needs of Maui's homes and businesses.
PRODUCTS - HC&S raw sugar is
shipped to Crockett, California for refining. It then goes to market
in the western two-thirds of the United States under the C&H cane
sugar label. Molasses is also marketed on the mainland, while a small
amount is sold directly to Maui cattle feeders.
HC&S also produces premium raw sugars under its Maui Brand Hawaiian
Raw Sugar label. Maui Brand Hawaiian Raw Sugar comes in two varieties,
Natural Hawaiian Raw Sugar and Premium Hawaiian Turbinado.
Both retain some of the natural molasses to bring extra richness to
all your sweetening needs. Maui Brand Hawaiian Raw Sugar products are
packaged in sizes from single serving packets through one-ton supersacks.
