  abstract = {{T}he use of organic matter ({OM}) amendments is widespread in tropical countries and may be beneficial for soil carbon storage. {I}nteractions between earthworms and {OM} amendments in tropical soils are largely unknown. {T}he aim of this study was to investigate the effect of bioturbation on the quantity and chemical composition of {OM} in soil amended with compost and vermicompost. {O}ur approach included comparison of soil samples amended with compost, vermicompost or chemical fertilizers in the presence or absence of earthworms during a one-year greenhouse experiment. {T}he soils were submitted to a regular cultivation cycle. {A}fter one year, we analysed bulk samples for soil {OM} elemental composition and characterised its lignin and non-cellulosic carbohydrate components. {O}ur results showed a decrease of the carbon and nitrogen content in soil amended with chemical fertilizers. {V}ermicompost amendment led to unchanged {OC} content, whereas the compost amendment increased the soils {OC} content compared to initial soil. {T}he addition of earthworms reduced {OC} and {N} content in soils with organic amendments. {T}his is in contrast to soil amended with mineral fertilizer only, where the presence of earthworms did not have any effect. {B}ioturbation influenced the lignin signature of the soils, and to a lesser extent the non-cellulosic carbohydrate signature. {I}n conclusion, compost amendment combined with bioturbation influenced the quality and quantity of {SOM} and as result carbon storage and its biogeochemical cycling in tropical soils. {I}mplications for soil fertility remain to be elucidated.},
