Across the American heartland, farmers are bringing in their harvest under conditions that have quietly become untenable. Diesel fuel has reached $6.50 a gallon — a record that arrived in a single month — while trade wars and tariffs have narrowed the markets and raised the costs that agriculture depends on. The harvest season, which should be the moment a year's labor converts to income, has become instead a reckoning with forces far beyond any one farmer's control. What unfolds in these fields this autumn may quietly determine what gets planted — and by whom — next spring.
