Soil inorganic nitrogen (N) determination. Y-axis indicates NO3- and NH4+ by mg N/kg of dried soil. X-axis indicates treatments. BS1: bacterial community from soil 1; BS2: bacterial community from soil 2; S1: natural soil 1; S2: natural soil 2; PS1: phage community from soil 1; PS2: phage community from soil 2; PC: phage cocktail. Y-axis scale of the natural soils (c) is different from the other plots (a and b). *Significant differences in pairwise comparisons (n = 5) between natural phage suspension (blue) vs control autoclaved phage suspension (orange) (Tukey’s HSD test, p ≤ 0.05)
