 หัวเรื่อง:การลดปริมาณวัตถุมีพิษทางการเกษตรในดินด้วยอีเอ็ม ผู้เขียน: Poonsook Haruthaithanasan, Piboon Boonsri สื่อสิ่งพิมพ์:pdf AbstractThe objective of this study is whether the efficiency of EM to degrade pesticide residues in soil. The experiments were carried out in RCB by using 2 pesticides at the rate of application 100 and 30 mg/kg of methyl parathion and carbofuran respectively. There were 6 treatments with 3 replications in each. After being spiked with the pesticides the soils were applied with 3 EM formulars and molass and including 2 controls. Consequently, the samples were collected at intervals 0,3,7,10,15 and 20 days to be analysed their residues. The results show that every treatment, not including the soil without pesticides spiked, was not different in residue concentrations especially at 25 days. However, the rate of degradation in controls were slightly higher than those in the EM treatment. |
