TABLE 3.

Recovery of viable E. coli O157:H7 strain B6914 from leachate and soil during two 18-day experiments in which intact (no-till) and disturbed (tilled) soil cores were used^a

^aAll values are means based on two replicates. 

^bIn each experiment the total amount for leachate samples was calculated by adding the amounts obtained after eight 25.4-mm rainfall events over a 17-day period (Fig. 1 and 2). The total amount for soil samples was calculated by adding the amounts obtained for three 50-mm layers plus the amount obtained for a manure layer if applicable; samples were obtained 18 days after inoculation.
