  abstract = {{O}rganic fertilizer application is often touted as an economical and effective method to increase soil fertility. {H}owever, this amendment may increase dissolved organic carbon ({DOC}) runoff into downstream aquatic ecosystems and may consequently alter aquatic microbial community. {W}e focused on understanding the effects of {DOC} runoff from soils amended with compost, vermicompost, or biochar on the aquatic microbial community of a tropical reservoir. {R}unoff collected from a series of rainfall simulations on soils amended with different organic fertilizers was incubated for 16 days in a series of 200 {L} mesocosms filled with water from a downstream reservoir. {W}e applied 454 high throughput pyrosequencing for bacterial 16{S} r{RNA} genes to analyze microbial communities. {A}fter 16 days of incubation, the richness and evenness of the microbial communities present decreased in the mesocosms amended with any organic fertilizers, except for the evenness in the mesocosms amended with compost runoff. {I}n contrast, they increased in the reservoir water control and soil-only amended mesocosms. {C}ommunity structure was mainly affected by p{H} and {DOC} concentration. {C}ompared to the autochthonous organic carbon produced during primary production, the addition of allochthonous {DOC} from these organic amendments seemed to exert a stronger effect on the communities over the period of incubation. {W}hile the {P}roteobacteria and {A}ctinobacteria classes were positively associated with higher {DOC} concentration, the number of sequences representing key bacterial groups differed between mesocosms particularly between the biochar runoff addition and the compost or vermi-compost runoff additions. {T}he genera of {P}ropionibacterium spp. and {M}ethylobacterium spp. were highly abundant in the compost runoff additions suggesting that they may represent sentinel species of complex organic carbon inputs. {O}verall, this work further underlines the importance of studying the off-site impacts of organic fertilizers as their impact on downstream aquatic systems is not negligible.},
