Grazing Corn Residue: Have received some questions on corn residue management. Cattle grazing can be a beneficial way of residue management if one has access to cattle. Note: I’ve been seeing quite a bit of black nightshade and some horsenettle, particularly in corn fields that had wind damage. Both species have poisonous leaves (increase concentration as plants age) and berries (decrease concentration as berries ripen). Frost doesn’t change toxin levels. UNL forage specialists say when cattle graze corn fields containing nightshade species, there’s enough dilution with the grain, leaf, and husk that poisoning shouldn’t be an issue. We’d recommend watching the cattle as some may prefer grazing the nightshade.
