Colorado's agriculture exports have hovered in the $2 billion range for the past two years. Exports include livestock, grains and beer. Exports have quadrupled since the 1990s and has steadily grown. Some dips came in 2015, when the strength of the U.S.dollar was the equivalent of a price hike, which caused demand to sour. Last year, the trade war started with China in April. So far, 2019 is trending down with the value of ag exports between January to July being down 15% from the same period last year. The decline is blamed on ongoing U.S. trade war tensions.
