Interactive dashboard: US heat wave hits corn and soy crops


Last week's heat wave across the central and southern US stressed the developing corn and soybean crops, causing the USDA to cut its ratings for both this week.

The USDA rated 63% of the US corn crop good to excellent, versus 66% a week ago. For soybeans, 64% of crop was rated good to excellent, down one percentage point from a week ago.
