It has been considered by environmental researchers and municipal managers, that earthworms can used to convert organic waste and animal excreta to vwermicompost. Organic matters change markedly in the earthworm`s digestion system. In this study, the effect of sugar beet molasses, aeration, and soil on chemichal-physical properties and maturity of vermicompost was investigated. This experiment was carried out using nine different treatment with three replication in a completely randomized design. The results showed that total organic carbon (TOC) decreased dut total nitrogen, phosphorus and potassium increased during 100 days of incubation. In addition, nitrate concentration and available phosphorous and potassium increased in all treatment at the end of 100 days incubation. The amount of ammonium decreased noticeably. Electrical conductivity (EC) of all treatment increased but their acidity decreased. Bulk and particle density increased but total porosity of all treatments decreased significantly. Water soluble carbon (WSC), ADF (Lignin + Cellulose), NH4:NO3 and C:N (maturity indices) decreased in all treatments.
