Rain in the US Farm Belt over the next five days is expected to cause further delays to soyabean plantings that have already been hampered by wet weather, analysts said.
"Temperatures will remain a bit cooler than normal across the corn belt over the next few days, which will continue to slow germination and early growth of corn and soyabeans," weather firm Maxar said.
Weekly US soyabean export sales came in at 771,600 tonnes, according to the US Department of Agriculture. That was near the high end of expectations for 200,000 tonnes to 800,000 tonnes.
