According to the National Agricultural Statistics Service, the value of Washington’s agricultural production was $10.2 billion in 2013. (Up from $9.97 billion in 2012.) This is a new record high. Additionally, “Record high values of production were established for five of the top ten Washington commodities, including milk, potatoes, cattle and calves, grapes, and pears.”
As shown in the table below, apples are still Washington’s highest value agricultural commodity ($2.2 billion), though their value declined by 11.8 percent from 2012 to 2013. Milk is now second ($1.3 billion), as wheat falls to third ($1.0 billion). Hops jumped up quite a bit, from 14th to 10th — a 40.3 percent increase in value.
