A short but intense growing season provides good potential for Alaska commercial agriculture, although the expense of getting agricultural products to market is a limiting factor. International export opportunities are being developed. Alaska's 590 farms covered 920,000 acres (372,324 hectares) in 2002. Hay, potatoes, lettuce, cabbage, carrots, beef, pork, dairy products, and greenhouse and nursery items are common commodities produced. In 2002, hay production was 26,000 tons, valued at $5,590,000; potatoes, 154,000 hundredweight (6,985,200 kg), $3,065,000; and barley for grain, 158,000 tons, $561,000 The leading farming regions of Alaska are the Matanuska Valley, northeast of Anchorage, and Delta Junction, north of Fairbanks.
