Fig. 1. Concentrations of E. coli RS2G recovered from soil core leachate samples after one or more 50.8-mm rainfall events at different times following manure application. (A) The symbols indicate samples obtained from cores that received a rainfall event on the 4th, 8th, or 16th day after manure application. (B) The symbols indicate samples obtained from cores that received three rainfall events on the 4th, 8th, and 16th day after manure application. Since there was no statistically significant effect of manure application on RS2G concentrations in the leachate, the three replicate cores for each manure application procedure were pooled to generate a total of nine samples per rainfall event.
