Microbial biomass and specific activity of 13C from added organic N fractions in the Jyndevad and Askov soils. Total PLFA after 14 days of incubation in control added water, the 1–10 kDa fraction, and the > 100 kDa fraction for the low, medium and high pH Jyndevad soils (a), Total PLFA after 14 days of incubation in control added water and the > 100 kDa fraction for the unfertilized (UNF), mineral fertilized (NPK), and animal manure (AM) fertilized Askov soil (b), Specific 13C incorporation in gram-positive, gram-negative and fungal PLFAs in Jyndevad soils added the 1–10 kDa fraction (c), Specific 13C incorporation in gram-positive, gram-negative and fungal PLFAs in Jyndevad soils added the > 100 kDa fraction (d), and Specific 13C incorporation in gram-positive, gram-negative and fungal PLFAs in Askov soils added the > 100 kDa fraction (e). Significant differences within treatments are marked by different letter above the bars (error bars are s.e.m., n = 4).
