  abstract = {{L}arge inputs of woody debris to soil can improve the soil. {W}e examined the fate of woody debris buried in soil after fire-free forest conversion to cropland in {F}rench {G}uiana. {W}e measured the mass loss of woody debris >4mm on five sampling dates for 4years after deforestation. {C}omposition of the organic matter of woody debris was analysed with {R}ock-{E}val pyrolysis, which enabled us to distinguish a labile carbon pool ({C}-lab) and a resistant carbon pool ({C}-res). {D}ecomposition of woody debris followed a first-order function with a half-life of 17.6months. {D}uring the decomposition of woody debris >4mm, the {C}:{N} ratio, hydrogen index ({HI}) and pyrolysed carbon below 400 degrees {C} ({R}400) decreased, suggesting that decarboxylation and dehydrogenation of woody debris occurred. {B}oth {C}-lab and {C}-res stocks decreased with time, but the decrease in {C}-lab was faster. {T}here was little humification of the debris and no long-term biogeochemical preservation of a woody debris fraction, which accords with the first-order decay observed. {W}e conclude that the benefits of ligno-cellulosic inputs for soil organic carbon contents in a tropical humid climate occur during the first year following deforestation.},
