From Agrimoney:

Wet weather has held back corn sowing in the US to its slowest since at least the 1980s, with planting grinding to a halt in some states, and the pace of seedings of other crops too at historically low levels.

US farmers sowed just 4% of their corn crop last week in what is typically one of the busiest weeks of the spring planting season, taking total seedings to 13% of expected acres, US Department of Agriculture data showed.

This was behind market expectations and the 40% typically sown by the beginning of May, with 66% in the ground last year, which had boasted excellent planting conditions – in marked contrast with the heavy rains, and cold, which have held up field work this year.

"The corn planting pace is the slowest since the data was compiled in the 1980s," Ker Chung Yang at Singapore-based broker Phillip Futures said, noting that Illinois, America's second-ranked corn producing state, Indiana and Ohio failed to show any progress.
