Vermicomposts from organic materials based on waste activated sludge obtained from the purification of municipal sewage were produced during the vermicomposting process with Eisenia fetida (Sav.) and for comparison fermented farmyard manure were incubated with two soils materials (Slightly loamy sand and loamy sand). In 30, 60, 90, 120 and 360 days of incubation the concentration of available and total phosphorus was determined. The biggest percentage part of available phosphorus in relation to the total content (mean for both soil materials) was stated for vermicompost produced from FYM and the smallest for vermicompost got from the mixture of waste activated sludge, sawdust and waste from meat processing factory
