Fig. 5

Root growth (a) and density (b) in NH4-Depot and non-Depot row-sides (Field 2014 and 2015). NH4-Depot side of maize row with concentrated stabilized (NH4)2SO4 solution placed as a depot at 10 cm depth; No depot other side of maize row without an NH4 +-fertilizer depot; BE bio-effector, NoBE no bio-effector, BE1 Pseudomonas sp. DSMZ 13134. Different letters between BE levels show a significant BE-effect, **P < 0.01 (Two-Way ANOVA, Tukey test, α = 0.05). There was no BE-effect in 2015. There was strong NH4-Depot-effect on RLD in both 2014 (P < 0.001) and 2015 (P < 0.001)
