Crop Progress
Weekly phenological stages for wheat, corn, and soybeans: current season vs 5-year average from USDA NASS and CéréObs.
Methodology
CéréObs (France) : FranceAgriMer publishes this survey every Friday. Plots are rated on 5 levels: very good, good, fairly good, poor, very poor. The good + very good score groups plots whose yield exceeds the five-year average.
USDA NASS (États-Unis) : USDA NASS releases its report every Monday, on the same 5-level scale. On the CBOT, the G+E (Good + Excellent) score is what traders look at first.

Crop condition ratings are a key leading indicator for grain prices on Euronext and CBOT. CéréObs surveys several hundred reference plots distributed across all French cereal-growing regions every week from April to July. Each plot is rated on a five-level scale: very good, good, fairly good, poor, very poor. The combined "good + very good" score is the benchmark watched by analysts and traders.
USDA NASS conducts an equivalent weekly survey in the United States, covering winter wheat states (Kansas, Oklahoma, Texas, South Dakota, Nebraska, Colorado, Montana) and the main corn and soybean states. The "Good + Excellent" (G+E) score is the reference figure published every Monday evening. A G+E rating below 50 % at heading is historically associated with below-average yields on the CBOT.
Crop progress data (planting, emergence, heading, harvest) complement condition ratings and are also published weekly by USDA NASS from April to November.
