Preliminary measurements of grain wasted by field-feeding mallards / by Lawson G. Sugden and D. Wayne Goerzen.: CW69-9/104E-PDF

"When waterfowl, particularly ducks, feed on swathed grain they not only eat the grain but also waste some by trampling and fouling. To the farmer who loses both ways, it matters little whether the grain is eaten or wasted. It is, however, of concern to the crop protection manager, who tries to make the most efficient use of lure crops, and who must evaluate feeding programs in terms of benefit/cost"--Introd.
