USDA allocates a share of the anticipated U.S. sugar market to sugar producers annually. This allotment basically determines the amount of sugar an individual company is allowed to sell that year. However, these allotments can be, and often are, adjusted based on harvest conditions.
More than 60% of the worlds sugar production is from sugar cane and the balance is from sugar beet. Approximately 10% of the sugar cane can be processed to commercial sugar and uses approximately 20 cubic meters of water per metric ton (m 3 /t) of cane processed.
