This NebGuide discusses the methods used by the hail insurance industry to assess yield loss due to hail damage in soybeans. A hailstorm can cause yield losses in soybeans ranging from slight to total destruction of the crop. Extensive research has been conducted to accurately predict the effects of hail damage on soybean yields. Results from these studies are used by hail insurance companies to assess yield losses and consequent adjustment made to clients. The information in this NebGuide should be valuable to producers facing replant decisions, and may also be useful in cases of insect damage. Yield loss predictions are based on two factors: a) stage of growth at the time of damage, and b) the degree of plant damage. Plant damage is classified as leaf defoliation, stand reduction, stem damage, and pod damage.
