U.S. growers intend to harvest 57.6 million acres of all types of hay in 2011, according to USDA’s June 30 Acreage report. That’s down 4% from the 2010 number and also down sharply from the nearly 59 million acres USDA had projected would be harvested in its March Prospective Plantings report (see April 5 eHay Weekly).

All-hay harvested acres are expected to be below or equal to last year for most states in the Corn Belt, Great Plains, Pacific Northwest and Rocky Mountain regions. Record-low harvested acreage is expected in Iowa, Nebraska, Minnesota, Maine, Pennsylvania and Wisconsin, while record-high acreage is expected in Arkansas.

For alfalfa and alfalfa mixtures, USDA expects a harvested area of 19.3 million acres, 3% fewer than in 2010.
