{"product_id":"9781288675074","title":"Agriculture as a Source of Barge Demand on the Upper Mississippi and Illinois Rivers: Background and Issues","description":"Five of the nation's top agricultural production states, Iowa, Illinois, Minnesota, Missouri, and Wisconsin have traditionally relied on the Upper Mississippi River-Illinois Waterway (UMR-IWW) navigation system as their principal conduit for export-bound agricultural products mostly bulk corn and soybeans. The low-cost, high-volume capability of barge transportation has long provided an important competitive advantage for U.S. agricultural products in international markets. Agricultural barge freight on the UMR-IWW grew rapidly for several decades in the post-WWII era, but has leveled off since the early 1980s. There is disagreement over the cause for this lack of growth in barge demand.","brand":"Bibliogov","offers":[{"title":"Default Title","offer_id":48533814280433,"sku":"9781288675074","price":15.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/5433\/7265\/files\/9781288675074_p0.jpg?v=1786329239","url":"https:\/\/shop.barnesandnoble.com\/products\/9781288675074","provider":"Barnes \u0026 Noble","version":"1.0","type":"link"}
