Soybean Loss Chart (Row-Crop Heads)

To determine soybean losses, operate the row-crop head in from the ends of the field and where the crop is typical of the entire field. Stop and back the combine (4.5 m) 15 ft. away from standing soybeans.

Mark off an area from where drive tire tracks stop (A), 0.6 m (2 ft.) to point (B). Now mark off header width. Check this area (C) for losses.

Soybean losses are determined by counting the number of beans in the plot for any or all of the following types of gathering losses.

1. Stubble Loss: Pods left attached to stalk stubble.
2. Uncut Stalk: Lodge or down stalks not gathered by the row-crop head.
3. Cut Stalk Loss: Stalks cut but lost in the gathering process.
4. Pods: Loose pods detached from stalks.
5. Shatter: Loose soybeans on the ground.

Pre-harvest losses (loose soybeans and pods in the rows) are generally low and can be included in the total loss count.

The above soybean loss figures are based on approximately 2600 soybeans per lb. (0.45 kg).
