Meteorologist Gail Martell of MartellCropProjections.com says farmers worked to accelerate corn planting this week, but in many cases are "mudding" in seeds after extremely wet conditions.
"Fifty percent of the U.S. corn area was extremely wet in April, meriting much-above normal or record wet standings in the 118-year data-set. Top corn states Iowa and Illinois are among the wettest," says Martell. "Whenever weather records are broken it is detrimental for crops. There will be a yield penalty to pay for severe planting delays in corn. North Dakota the top spring wheat state experienced the coldest April on record, Minnesota the 3rd coldest. This explains the delayed snowmelt and cold soil temperatures that set back spring planting. Only one-fourth of wheat was sown by May 12, compared to 65% normally."
