There's a rather old (by now) but famous university study in which scientists and researchers determined that mulching is better for lawns than bagging is. Everybody continually cites the study when talking about mulch mowing as opposed to bagging, but as famous as the study is, I can't seem to find it (or info on it) on the web. If anybody can cite the study, the year done (I'd guess about 1980 or '85), and the institution that did the study, I'd appreciate it if you'd post it here. Many thanks!!
