Effect of different feeding materials on the trace and nutrient elements of vermicompost using Eisenia fetida ; Farklı besleme materyallerinin Eisenia fetida kullanılarak oluşturulan vermikomposttaki bazı besin elementleri ve ağır metal değişimine etkisi

The aim of this study was to determine the influences of different feeding materials on the physico-chemical parameters of vermicompost using Eisenia fetida (Savingy, 1826). In this study, four treatments, with the same conditions in terms of organic wastes type were prepared to produce vermicompost from hazelnut husk (% 100), tea plant waste (0), hazelnut husk (A) (% 50) + tea plant waste (B) (50%), hazelnut husk (A) (30%) + tea plant waste (30%) + cow dung (20%) + sawdust (15%) + waste newspaper (%5) using earthworms. The standard laboratory analysis methods were used to determine the physical and chemical parameters in the different produced vermicomposts. The mean N content in the growing medium A, B, C, and D was 1.41%, 2.5%, 1.96%, and 1.47% respectively. The mean phosphorus content in the growing medium A, B, C, and D was 807.69 mg/kg, 1748.25 mg/kg, 1491.25 mg/kg, and 1410.75 mg/kg respectively. The mean potassium in the growing medium A, B, C, and D was 11244.69 mg/kg, 7790 mg/kg, 6884.25 mg/kg, and 8006.25 mg/kg respectively. Compared to the initial vermibed mixture, the N, P, and K content was higher in all the growing mediums. The Pb, Cd and As content was lower in all the growing mediums in the final compost than the initial vermibed mixture. Eisenia fetida is very effective in converting some waste materials into a high-quality compost and decreasing the heavy metal content in the final vermicompost more than in the initial vermibed mixture. ; Bu çalışmanın amacı, farklı besleme materyalleri ile Eisenia fetida (Savingy, 1826)’nın beslenmesi sonucunda oluşan vermikomposttaki bazı fiziko-kimyasal parametrelerin tespit edilmesidir. Bu amaçla, fındık kabuğu (A) (0), çay bitkisi atığı (B) (0), fındık kabuğu (C) () + çay atığı (), (D)fındık atığı () +çay atığı () +inek gübresi () +talaş () + atık kağıt (%5) oluşan besi ortamlarında rastgele yönteme göre dört tekrarlı denemeler kurulmuştur. Araştırma sonucunda elde edilen vermikomposttaki bazı fiziko-kimyasal parametreler standart laboratuvar testleri ile ...
