If you grow soybeans, UW-Extension has a new website, CoolBean.info, dedicated to soybean research and information for growers. The site also includes information about small grains: barley, oat, and wheat. The site is sponsored by the Wisconsin Soybean Extension Program and the Wisconsin Soybean Marketing Board.
One report on the site that may be of interest is Think Twice Before Replanting Soybeans. The report is based on a study conducted in 2012 and 2013 at the Arlington Agricultural Research Station in Wisconsin.
