Technical Abstract: This field experiment was designed to look at survival rates of bacterial groups after addition of three nutrient sources to tall fescue fields. The nutrient sources were inorganic fertilizer (I), poultry littler (PL) and dairy manure (DM) along with a control treatment (C). P and K concentrations were similar in all fertility treatments except C. Zn concentrations were higher in no-till compared to tilled fields. DM and PL had the highest Zn levels. DM and C treatments did not change Enterococci populations over time with similar populations to day 0. Enterococci populations spiked day 1 through 15 with the PL treatment with day 4 being highest.
