a Sample sites were as follows: PS (amended), pig slurry amended with 25.58 mg liter−1 SCP and 18.85 mg liter−1 OTC; PS (control), unamended pig slurry; preapp (soil), soil cores from year 1 before slurry application; 1,1 (soil), soil cores from year 1, day 1 time point; 1,289 (soil), soil cores from year 1, day 289 time point; 2,1 (soil), soil cores from year 2, day 1 time point; soil leachate (three combined samples collected over the sample period from large rainfall events).
