Material handling losses and corn quality changes were measured in three typical on-farm corn-drying systems. Handling losses averaged 0.78% of initial weight, with a range of 0.40% to 1.71% of initial weight. There was no indication that handling losses were related to initial moisture content. Handling losses were less than would have been assessed in shrink had the corn been delivered wet to a grain buyer. Test weight increased during drying, but the simplified Hall and Hill test weight adjustment table overpredicted these increases.
