Abstract: A Farmers’ field trial was conducted at Patratu (Ramgarh) to study the effect of lime, compost, plant growth promoting rhizobacteria and arbuscular mycorrhizal fungi for remediation of high trace metal levels in mustard-maize cropping system. Results reveal that microbial inoculants with or without vermicompost increased the trace metal removal, however, vermicompost alone decreased the removal. Vermicompost, lime and lime + vermicompost significantly reduced the total Cd uptake by mustard and maize. Inoculation with Glomus mossaeresulted in elevated level of Cd in mustard and maize plants. Total trace metal content in soil was significantly reduced by microbial inoculation alone or that in combination with vermicompost. However, DTPA-extractable trace metals decreased with addition of amendments as well as inoculation of microbes. Glomus mossae was most effective in remediating the trace metals. under this study, the total metal content reduced effectively by their inoculation alone while inoculation along with vermicompost resulted in reducing the DTPA-extractable fraction, more effectively. The extent of reduction in total Cd and Pbafter harvest of both crops was 6 to 26 and 5 to 12per cent, respectively over control. However, the corresponding values observed for DTPA extractable Cd and Pb was 53 to 65 and 20 to 32per cent over control in microbial inoculation and 46 to 47 and 14 to 17per cent in case of amendments.
