Decrease in log (CFU/g dry weight) counts (n = 4 per time point and experimental variant) of Salmonella strains in different treatments and soil types shown as slopes of linear regressions. Values represent means of slopes from lettuce and corn salad samples for the different treatments in log (CFU/day). For a better readability, the color code indicates a range between high and low decrease in CFU (red and yellow color, respectively).
