The United States has almost half of the corn crop planted for the season at 45% complete, according to the United States Department of Agriculture (USDA) Crop Progress Report on May 2.


The USDA reported 57% of corn planted in Iowa as of May 1, with the 5-year average being 28%. The weekly report had 7% of corn emerging in Iowa, which is 4% ahead of the 5-year average.


The Crop Progress Report showed 7% of soybeans had been planted in Iowa as of May 1, 1% behind this time last year, but still leading the 5-year average by 4%.
