Cranberry harvest in New Jersey
Cranberries are a major commercial crop in the U.S. states of Massachusetts, New Jersey, Oregon, Washington, and Wisconsin, as well as in the Canadian provinces of British Columbia, New Brunswick, Ontario, Nova Scotia, Prince Edward Island, Newfoundland and Quebec. 20% of the world's cranberries are produced in British Columbia's lower mainland region . In the United States, Wisconsin is the leading producer of cranberries, with over half of U.S. production. Massachusetts is the second largest U.S. producer. A very small production is found in southern Argentina and Chile, the Netherlands, and Eastern Europe.
Historically, cranberry beds were constructed in wetlands. Today cranberry beds are constructed in upland areas with a shallow water table. The topsoil is scraped off to form dykes around the bed perimeter. Clean sand is hauled into a depth of four to eight inches. The surface is laser leveled flat to provide even drainage. Beds are frequently drained with socked tile in addition to the perimeter ditch. In addition to making it possible to hold water, the dykes allow equipment to service the beds without driving on the vines. Irrigation equipment is installed in the bed to provide irrigation for vine growth and for spring and autumn frost protection.
Cranberry vines are propagated by moving vines from an established bed. The vines are spread on the surface of the sand of the new bed and pushed into the sand with a blunt disk. The vines are watered frequently during the first few weeks until roots form and new shoots grow. Beds are given frequent light application of nitrogen fertilizer during the first year. The cost of establishment for new cranberry beds is estimated to be about US$70,000 per hectare (approx. $28,300 per acre).
A common misconception about cranberry production is that the beds remain flooded throughout the year....
