The already late Upper Midwest harvest will be delayed even further after widespread, heavy rains in the middle of September. Crop conditions also suffered from the excess moisture.

The weekly crop progress report reflecting conditions as of Sept. 22 and released Sept. 23 by the National Agricultural Statistics Service, an arm of the U.S. Department of Agriculture, found that some wheat farmers made some progress during the week before the heavy rains hit.

For example, Montana farmers had harvested 80% of their wheat on Sept. 22, up from 69% a week earlier. Even so, the 80% rate was still well below the five-year average of 95% for Sept. 22.

One example of how crop conditions slipped during the week: 61% of North Dakota's soybean crop was rated good or excellent on Sept. 22, down from 64% a week earlier. Area farmers - many of whom will have difficulties getting into soggy, unharvested fields - will pay close attention to crop conditions.

Here's a closer look at wheat, corn and soybeans, the region's three major crops.
