Wheat
Production by country and the world's biggest exporters — the staple crop traded more than any other crop combined, historically.
Corn
Production by country and the world's biggest exporters — the world's highest-volume grain, and the second-most traded by tonnes.
Soybean
Production by country and the world's biggest exporters — the most concentrated major food trade: two countries supply ~85% of global exports.
More on the way: other staple crops (rice, and others) and key agricultural trade goods — each getting the same treatment: real figures, real sources, on a map.
