Warm weather allowed many Iowa farmers to finish planting their soybean acres last week. The state’s 2017 soybean crop was 91% planted as of June 4, according to the latest weekly USDA survey. “It was another warm, dry day yesterday [June 5], and we were able to get done with soybeans,” says Roger Nowatsky, who farms in Linn County in eastern Iowa. “We had to make a decision about whether or not to replant a poor stand of about 20 acres of earlier-planted beans, and we went ahead and replanted.”
The weekly statewide survey by USDA’s National Ag Statistics Service showed 90% of the state’s corn crop had emerged as of June 4, about six days behind last year. Corn condition improved and is now rated 77% good to excellent. Iowa’s soybean crop is rated 73% good to excellent, based on this year’s first assessment.
Good week to finish planting, make hay and spray
“It was a very good week of weather for farmers to finish planting, make hay and do needed spraying. The warm sunny weather was also very good for crop conditions with 77% of corn and 73% of beans rated good or excellent,” noted Iowa Ag Secretary Bill Northey. Farmers had six suitable days for fieldwork last week, the most Iowa has had all spring. One-third of the first cutting of alfalfa hay was harvested last week. Hay conditions improved to 85% good to excellent.
