Sandy soils properties with low nutrients availability and high porosity could be improved with the combination application of biochar-compost to increase the plant productivity. The objective of this study was to examine the impacts of different rates compost-biochar addition on sandy-loam soil properties and cabbage (Brassica chinensis L. var. parachinesis) growth performance. The oil palm empty fruit bunch biochar was pyrolyzed at temperature ranging between 450 to 500°C. Different rates of biochar-compost combination of 0 until 20 t/ha-1 were arranged in a randomized block design in the greenhouse. The cabbage was planted in the arranged polybag and plant growth parameter (leaf number, plant height and chlorophyll content) were measured. The incorporation of 10 and 20 t ha-1 biochar-compost with soil were showed significant increased in soil pH when compared to the non-amended soil. The application of highest rate which is 20 t ha-1 biochar-compost increased the soil exchangeable bases. Positive effects of biochar-compost addition also were found on plant height and dry weigh biomass at all application rates. The study showed that the application of biochar-compost has the potential to improve soil chemical properties and plant productivity.
