Crop Damage

Hail damaged corn — Corn around V10-11 with leaves stripped due to hail damage. In this case, much of the corn will recover and look better in 10-14 days. Watch stalk bruising to see if stalk rot sets in. There are fields with hail damage at lower stalks with weakened plants that easily break. Soybeans at R1 (beginning flowering) reduced to sticks north of Stromsburg and in Hordville area. Soybeans with damage like this at the R1 stage can have the greatest yield loss in spite of seeing new buds regrowing with the warm weather. Another concern will be weed control going forward.

Mid-Season Hail Damage Assessments in Corn and Soybeans

When severe storms and hail hit your corn and soybean fields, it's important to estimate yield losses to determine the need for future inputs and alternative management strategies. This guide offers steps to evaluate mid-season hail damage and estimate potential yield losses.
