Specific recruitment of soil bacteria and fungi decomposers following a biostimulant application increased crop residues mineralization - Fig 2

Composition of the bacterial (a), fungal (b) and archaeal (c) microbial community in the various samples. Pristine microbial composition of the BS and straw (“Input”) and composition of the bacterial, fungal and archaeal communities at the phylum level (and class level for the Proteobacteria and archaea) in the three soil treatments after 7 weeks (49 days) of incubation with the associated richness and Shannon diversity index. BS: biostimulant samples, CS: control soil, SS: soil with straw, SBS: soil with straw and BS, Means and standard errors were calculated (n = 3). The Kruskal-Wallis test was performed (P<0.05). Different letters correspond to significantly different values.
