Crop monitoring service MARS revised its forecasts for EU crops in September, lowering the average yield estimates for corn and sunflower due to heat impacts in eastern Europe, while increasing soybean and sugar beet yields. The heatwave and dry conditions in several countries, including Romania, Bulgaria, and Hungary, shortened the grain filling period and reduced biomass accumulation. Dry weather in Poland, Lithuania, and northeastern Germany also affected corn yields. In contrast, favorable weather in western Europe allowed for increased yield forecasts. The European Commission also lowered its yield forecasts, following MARS's lead, due to the adverse weather conditions.
