The soybean yield rating calculated by Farm Futures based on the condition ratings came in at 50.3 bushels per acre, which is close to USDA’s current 50.6. Yield potential improved in nine states, was unchanged in three and declined in six. The declines included 0.1 bpa slippage in each Iowa and Indiana.

Farm Futures’ calculated average corn yield was about unchanged at 172.4 to 174.1. USDA is at 174.4. Yield potential improved from a week ago in six states, including Iowa (up .5 bpa) and South Dakota (up 1.3).

Iowa reported another wet week. Fieldwork was limited to 3.3 days statewide, but in the drier east central and southeast areas farmers had five days or more. Standing water was reported in some fields in the northern third of the state.

Drier conditions in Indiana allowed corn harvest to reach 7% and soybeans 2%. Some farmers have reported white mold and diplodia ear rot in the corn. In soybeans, there were reports of weed pressure, which led to lodging and increased risk for mold, Indiana said.

Winter wheat planting advanced to 17%, compared with 16% a year ago and the 16% average. USDA will add wheat emergence to next week’s report.

In Kansas, the winter wheat was 9% planted, which matched last year and the five-year average. Three to five inches of rain fell in the northeast part of the state, while the southwest remained dry. Statewide topsoil moisture was rated 16% surplus, 72% adequate, 9% short and 3% very short.

Spring wheat harvest was at 98%, compared with 99% a year ago and the 93% average.  North Dakota’s harvest was at 98% harvested versus the 91% average. This will be the final national spring wheat harvest report for the season.

Nationally, sorghum was 29% harvested and 51% mature versus the 30% and 49% averages. The crop improved 1 point to 66% good to excellent.
