The corn harvest advanced to 35% completed, and the soybean harvest improved to 44% as of Sunday, with both three points behind the five-year averages, the U.S. Department of Agriculture said on Tuesday.
Crop ratings were unchanged for corn and soybeans, with corn at 73% good to excellent and soybeans at 74%.
Rain and muddy fields slowed harvest in Iowa, where there were 4.5 days for field work. Corn there was 19% harvested and soybeans 43% harvested, compared with the respective five-year averages of 32% and 54%.
Conditions were better in neighboring Illinois, where the corn harvest advanced to 62%, which was well ahead of the 51% average. There were 5.6 days for fieldwork, including for winter wheat planting, which reached 20%, compared with the five-year average of 30%.
The harvest in Indiana had a slow start last week because of wet fields, but dry weather got farmers in the fields later in the week, the state report said. Indiana’s corn harvest was 38% completed versus the 33% average, while soybeans were at 33% versus the 36% average.
“While the dry week was beneficial for harvest progress, it had little impact on the disease and mold presence that remains in the fields. Stalk strength continues to be a concern during harvest, but the overall condition of the (corn) crop remains stable,” the Indiana report said.
The national average corn yield potential calculated by Farm Futures based on the condition ratings were about unchanged, with a topside forecast of 173.3 bu. per acre. Calculations showed that, in the past week, yield potential increased in six states, decreased in five and was unchanged in six.
The calculated soybean yield potential also was unchanged at about 50.5 bu. per acre. Soybean yield potential improved in 10 states, was unchanged in four and declined in four compared to a week ago.
Winter wheat planting advanced to 59% completed, compared with 60% a year ago and the 60% average. Wheat emergence was 34%, versus 29% a year ago and the 30% average.
In Kansas, winter wheat was 58% planted and 29% emerged, which trailed the five-year averages. Statewide topsoil moisture was rated 12% surplus, 73% adequate, 11% short and 4% very short.
Nationally, sorghum was 48% harvested versus the 42% average. The crop rating slipped one point to 65% good to excellent.
