Soybean fields are nearing maturing across Iowa with minimal delay compared to 2016 due to cool temperatures. However, soybean sensitivity to day length speeds up crop development towards physiological maturity. During this time, senescence is occurring and carbohydrates are being converted to oils. Soybean seed moisture changes very little and remains near 60 percent during the de-greening period. As the pods turn to mature color at the beginning of maturity stage (R7), seed dry matter accumulation is complete and seed moisture rapidly decreases.
