Radioactivity distribution for transformation of 14C-salicylic acid in cattle (above) and pig (below) manure. Values are arithmetic mean values obtained from six experiments (cattle manure; three sites: NRW_1, NRW_2, BAY_1; sampling in winter and summer) and three experiments (pig manure; three sites: NRW_1, NRW_2, BAY_1) and six replicates per experiment. For standard deviation and COV, see Additional file 1: Tables S14 (cattle) and S15 (pig)
