In this study, the effect of extraction process on the compost structure and its plant growing characteristic was investigated. Compost samples (raw compost sample taken from compost production facility and compost samples extracted with Na(2)EDTA and Na2S2O5 mixture or molasses hydrolyzate) have been characterized and these samples structures were examinated by)(RD, SEM and IR analysis. The experiments of compliance with the plant (phytotoxicity experiments) have been conducted to determine the plant growing characteristic of the compost samples. When the results obtained from experimental studies were evaluated, it was determined that the best plant growing were achieved using 0.01 M Na(2)EDTA-0.1 M Na2S2O5 solution. The plant growing efficiency value was 97% for 25% compost:soil mixture. When the results obtained from studies were evaluated, it: was determined that extraction processes caused both remarkable changes in compost characteristics and compliance with plant.
