Ideal combinations of sun, water and mineral-rich alluvial soil make for perfect growing conditions for Washington State potatoes. Varieties of Washington potatoes grown in the Columbia Basin,Yakima Valley and Skagit Valley are known world-wide for high solids and premium quality. Potatoes represent the State’s third largest agricultural crop with a farm gate value of over $690 million, and total value to the State of over $3.5 billion. In 2009, Washington growers raised 145,000 acres of potatoes with an average yield of 61,000 lbs. per acre, 8,845,000,000 lbs. total. 87 percent of the Washington potato crop is sold to processors who transform them into golden fries, crunchy chips and creamy mashed potatoes. Washington potatoes are nutrient dense, have more potassium than a banana, the protein of half a glass of milk and provide almost half of your daily vitamin C needs.
