A Scientific Reports study using 2007-2016 cultivar trial data from 27 states finds that sowing soybeans about 12 days earlier would have raised US yields by 10% and generated roughly $9 billion in cumulative gains. Drought effects through vapor pressure deficit are also identified.
The study suggests planting-date adjustments could lift future US soybean output, a modest long-run bearish factor for soybean and meal prices if widely adopted.
After 363 past bearish weather events, SOY moved a median -0.6% over 5 sessions (42% higher; middle half -2.5% to +1.1%), and -0.2% over 20.
After 55 past neutral weather events, SBM moved a median -0.1% over 5 sessions (47% higher; middle half -1.7% to +1.5%), and +0.1% over 20.
