Among several methods used to assess maturity of compost, determina-tion of diethyl ether and choloroform extractable lipids seems to be a promising tech-nique as lipids are an important portion of all organic wastes. The aim of this paper was to monitor maturity parameters of compost piles made from different organic sources (cow manure, poultry slaughterhouse, and dairy industry) using different methods. Di-ethyl ether (DEE) and chloroform (CHCl3) extractable lipids have been measured during composting and compared to other parameters commonly utilized to study compost sta-bility and maturity (organic carbon, total and inorganic N, CO2 evolution rate, microbial biomass C, and phytotoxicity test). Results suggested none of these parameters may exhaustively describe maturity of composts studied
