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