Abstract
The increasing of intensive use of the inorganic fertilizer had affected to the high contamination of Pb and Cd in the agricultural land of paddy (Oryza sativaL). The extensive use of phosphorous fertilizer as the inorganic fertilizer which unfollowed by adequate use of organic fertilizer potentially contaminated the soil and plants. Finding the sufficient remediation technique of heavy metal contamination was one of most challenges. This study was aimed to investigate the potential of biochar and compost in the treatment of the contaminated paddy field. The procedures were employed to reduce the dissolved of Pb and Cd in soil by improvement the soil chemical properties. The Pband Cd concentration and its control was measured using Atomic Absorption Spectrophotometry (AAS). The data analysis were addressed by the variance analysis, ANOVA, using Random group. The further analysis had been exercised using Duncan’s multiple range test with an error rate of 5%. The optimum dosage of biochar and compost were determined using linear regression analysis. The results showed that the biochar had potential to reduce the contaminated Pb and Cd compared to adding the compost. The optimum dosage of straw compost, husk compost, straw biochar, and husk biochar was 7.90 ton.ha-1, 6.88 ton.ha-1, 7.59 ton.ha-1, and 9.85 ton.ha-1, respectively.
