Fig. 3. Vertical distribution of bromide and pesticides in the soil profile in 1998 in plots treated with different amendments [cow manure (CM), pig slurry (PS), or mineral fertilizer (MF)] and tillage practices [conventional tillage (CT) and reduced tillage (RT)]. Boxes end at minimum and maximum values measured at each sampling depth from the four sampling locations in each plot. Values below the detection limit were plotted as zero.
