"The vast quantity of agricultural products that North Dakota exports is a story shared by farm states across the country. American agriculture sent $129 billion worth of goods abroad in fiscal 2016 – more than 20 percent of all the food grown in the United States. That number has more than doubled over the past decade, making agriculture a rare bright spot in the U.S. trade accounts. When President Donald Trump and free-trade critics fret about the United States’ $500 billion trade deficit, it’s often lost that American farmers run a large and growing surplus, and have been since the 1960s. Last year the surplus was $16.6 billion. The USDA projects it will rise to $21.5 billion this year."
