  abstract = {{O}rganic amendments may improve the quality of acidic tropical agricultural soils with low organic carbon contents under conventional management (mineral fertilization and irrigation) in {S}outheast {A}sia. {W}e investigated the effect of biochar, compost and their combination on maize growth and yield, soil physical, biological and chemical properties at harvesting time at four sites in three countries: {T}hailand, {V}ietnam and {L}aos. {T}reatments consisted of 10 t.ha(-1) cow manure compost and 7 t.ha(-1) of {B}amboo biochar and their combination. {M}aize biomass production and cop yields were recorded for two seasons. {E}lemental content, p{H} and nutrient availability of soils were analyzed after the first growing season. {W}e also characterized macrofauna abundance and water infiltration. {F}ew changes were noted for maize biomass production and maize cop yield. {S}oil chemical parameters showed contrasting, site-specific results. {C}ompost and biochar amendments increased soil organic carbon, p{H}, total {K} and {N}, {P} and {K} availability especially for sandy soils in {T}hailand. {T}he combination of both amendments could reduce nutrient availability as compared to compost only treatments. {P}hysical and biological parameters showed no treatment response. {W}e conclude that the addition of compost, biochar and their mixture to tropical soils have site-specific short-term effects on chemical soil parameters. {T}heir short-term effect on plants is thus mainly related to nutrient input. {T}he site-dependent results despite similar crops, fertilization and irrigation practices suggest that inherent soil parameters and optimization of organic amendment application to specific pedoclimatic conditions need future attention.},
