Onion has been a key crop for Wisconsin’s commercial vegetable growers for a number of years, especially on muck soils. Most of the onions produced in Wisconsin are sold on the wholesale fresh market. Competition from other regions of the country has resulted in declining profit margins for onion growers and a slow decline in onion acreage in Wisconsin. Acreage on muck has also been taken out of production as the Wisconsin DNR has purchased property and has implemented permanent wetland restoration on many muck acres.
