This study aimed to use charcoal derived from the bamboo and melaleuca produced by traditional kiln applied to sandy soil growing mustard green (Brassica juncea L.). The charcoals were applied at three ratio (1%,2%, and 3%, which correspond to 10, 20, and 30 g charcoal/kg soil in pots) and the control treatment without charcoal. Soil properties were investigated including bulk density, pH, electrical conductivity (EC), cation exchange capacity (CEC), organic matter content, total nitrogen, and total phosphorous. The results showed that bulk density decreased in charcoal-treated soils. pH and EC were in the suitable range for plants.Nutrients and CEC of the soil in the charcoal treatment were significantly higher compared with the control (CEC increase 6.8% to 16%; TC increase 80% to 115%; TN increase 37.5 to 75%). Green mustard growing on charcoalamended soil had greater height (higher 3% to 21%), bigger leaves, and higher yield (increase18% to 81%) than those of plants groomed in the control treatment. This study showed the potential of using charcoal as supplying nutrient to the poor soil. Moreover, the abundant of raw material and easy to produce, it is suitable for applying in the Mekong Delta, Viet Nam, and other countries with similar conditions and infrastructure.
