Fig. 1. Experiment layout at the Saint-Lambert-de-Lauzon site, showing the plots sizes and treatments, the tile lines, and the access chambers. The drained surface for each plot was 750 m2 (1998) and 600 m2 (1999) for cow manure–reduced tillage (CM–RT), 1500 m2 (1998) and 1200 m2 (1999) for CM–conventional tillage (CT), and 1200 m2 for mineral fertilizer (MF)–CT, MF–RT, pig manure (PM)–CT, and PM–RT. See text for details concerning the changes in the drained surface for CM plots.
