An INPE bulletin says gradually improving soil moisture in Acre is expected to support summer planting and the development of soybeans and corn, including soybean flowering and grain filling. It also warns that above-average rain, particularly in January, could cause waterlogging and increase fungal disease risk; other parts of the Amazon may face drier, hotter conditions.
More favorable moisture could support crop development and production in Acre, adding some bearish supply pressure for soybeans and corn, while excessive rain could limit that benefit locally.
After 363 past bearish weather events, Soybeans moved a median -0.6% over 5 sessions (42% higher; middle half -2.5% to +1.1%), and -0.2% over 20.
After 357 past bearish weather events, Corn moved a median -0.3% over 5 sessions (44% higher; middle half -2.2% to +1.3%), and -0.5% over 20.
