North America's Great Plains are a common breadbasket shared between Canada and the United States. In Canada, the grain-growing areas are also called the Canadian prairies. Sometimes the province of Saskatchewan, also known for producing a huge supplement of potash, is further singled out from within this region as the main breadbasket of Canada. In the United States, this region is called the Corn Belt, or (occasionally) the "Grain Belt", and it generally extends from the Canadian border between the Rocky Mountains and the Great Lakes down through the Texas Panhandle.
Additionally, the San Joaquin Valley in California has also been called the "food basket of the world." The San Joaquin Valley produces the majority of the 12.8% of the United States' agricultural production (as measured by dollar value) that comes from California.[ Grapes - table, raisin, and to a lesser extent, wine - are perhaps the valley's highest-profile product, but equally (if not more) important are cotton, nuts (especially almonds and pistachios), citrus, and vegetables. 70% of the world's and 100% of the U.S. supply of almonds comes from the valley. Oranges, peaches, garlic, tangerines, tomatoes, kiwis, hay, alfalfa and numerous other crops have been harvested with great success. According to the 2002 Census of Agriculture’s ranking of market value of agricultural products sold, nine of the nation’s top 10, and 12 of the top 20, producing counties are in California. [
