Ham Kompost ve Ekstraksiyon İşlemine Tabi Tutulmuş Kompost Numunelerinin Karakterizasyonları ve Bitkiye Yarayışlılıkları Açısından Karşılaştırılması

Türkçe

In this study, the effect o f 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 Na2EDTA and Na2S2O 5 mixture or molasses hydrolyzate) have been characterized and these samples structures were examinated by XRD, SEM and IR analysis. The experiments o f compliance with the plant (phytotoxicity experiments) have been conducted to determine the plant growing characteristic o f 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 Na2EDTA-0.1 M Na2S2O 5 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.
