As of May 10, eighty-one percent of Iowa’s corn was planted and 24 percent was emerged, according to USDA-NASS. Some planting undoubtedly occurred since May 10. Good to excellent crop emergence reports come from across the state by ISU Extension Agronomists. There are a few reports though of less-than-desirable corn emergence due to crusting, poor seed bed, herbicide damage, etc. As the crop emerges, this is a great time for producers to assess their corn stands. What went well? What didn’t? What action should be taken?
