【 摘 要 】

This researchaims to monitor the humification process of domestic sewage sludge resultedfrom the vermicomposting, evaluating, also, the possibility of using the finalproduct (vermicompost) in agricultural soils. The monitored chemical variablesduring the 90 days of vermicomposting were: humidity rate, organic matter content,nitrogen and phosphorus content, pathogenic organisms concentration, total organiccarbon, acidity, CEC, C/N ratio, CEC/TOC ratio, and humic and fulvic acids content.The change in these variables during the vermicomposting process showed thatthis technique is effective for use in the maturation of the residue.
