Özet:

 Composting is the process of converting organic wastes into a soil improving product through biological processes.. In this study, the suitability of pomegranate processing wastes from fruit juice industry for vermicomposting was investigated by pre-composting with cattle manure, chicken manure and straw wastes. The vermicomposting process was carried out under laboratory conditions in five separate plastic containers of 38 L volume using Eisenia fetida species earthworms for 150 days. The physicochemical properties and germination index results of the vermicomposts obtained at the end of the application were evaluated. While the initial carbonnitrogen CN ratios of vermicompost mixtures were in the range of 11,70-12,50, these ratios decreased at the end of the process and realized in the range of 9,95-10,20. The highest earthworm reproduction was realized in the K4 mixture with 2.563 individuals; the highest mass and volume losses were experienced in the same mixture and these losses were calculated as 13,5 and 24,0, respectively. The resulting earthworm composts met the criteria of organic matter content 40 and CN ratio 8-22 as specified in the Türkiye national legislation. This has resulted in a soil amendment that is rich in organic matter and balanced in terms of carbon and nitrogen for plants. Furthermore, according to the germination index test, no phytotoxicity was observed at application doses of 25 and 50.

 Kompostlaştırma, organik içerikli atıkların biyolojik süreçler aracılığıyla toprak iyileştirici bir ürüne dönüştürülmesi işlemidir. Bu çalışmada, meyve suyu endüstrisinden kaynaklanan nar işleme atıklarının; sığır gübresi, tavuk gübresi ve saman atıkları ile birlikte ön kompostlanması sonucu elde edilen karışımların solucanlı kompostlaştırmaya vermikompostlamaya uygunluğu araştırılmıştır. Vermikompostlama işlemi laboratuvar şartlarında, 38 L hacmindeki beş ayrı plastik kapta, Eisenia fetida türü solucanlar kullanılarak 150 gün süreyle yürütülmüştür. Uygulama sonunda elde edilen vermikompostların fizikokimyasal özellikleri ve çimlenme indeksi sonuçları değerlendirilmiştir. Vermikompost karışımlarının başlangıçtaki karbonazot CN oranları 11,7012,50 aralığında iken, proses sonunda düşerek bu oranlar 9,9510,20 aralığında gerçekleşmiştir. Solucan çoğalması en fazla, 2.563 bireyle K4 karışımında gerçekleşmiş; aynı karışımda en yüksek kütle ve hacim kaybı yaşanmış ve bu kayıplar sırasıyla 13,5 ve 24,0 olarak hesaplanmıştır. Elde edilen solucan kompostları, Türkiye ulusal mevzuatında belirtilen organik madde oranı 40 ve CN oranı 822 kriterlerini sağlamıştır. Bu sayede bitkiler için organik maddece zengin ve karbon-azot açısından dengeli bir toprak iyileştirici elde edilmiştir. Ayrıca, çimlenme indeksi testine göre 25 ve 50lik uygulama dozlarında fitotoksisite gözlenmemiştir.
