The compost quality was improved by low concentration of fulvic acid through optimizing fungal structure
. In this study, the effects of FA on combined fermentation of straw and mushroom residue were studied by composting experiments with different concentrations of FA. The succession of prokaryotic and eukaryotic communities was investigated, together with the changing trends of various environmental factors, the effects of FA on composting were elucidated.
