a positive trendP= 0.079so close (0.05 < p ≤ 0.1)

Unlike the positive effect of BE addition on yield, the effect on root biomass was not significant but showed only a positive trend ( Figure 6A , RR= 1.11, P= 0.079; 95% C.I.: 0.99-1.24).

a negative trendno p-value reported

Although the yield RR was not significantly affected by the type of fertilizer applied (manure, ashes, soluble P, control (no P fertilizer), municipal waste composts, rock P, sewage sludge, digestates, biochar) (P=0.155; Figure 7 ), animal waste products tended to have the strongest increase in the RR of BE addition, whereas Biochar even showed a negative trend.

a weak trendno p-value reported

(2018) found a positive relationship between soil pH and yield response in their meta-analysis for P solubilizers in combination with N fixers, while for N fixers alone and P solubilizers alone, no and only a weak trend was found respectively.
