Özet
Şehir katı atıklarından elde edilen çöp kompostunun Xerofluvent toprakların fiziksel özelliklere etkisinin incelendiği bu çalışma, 2 yıllık tarla denemesi olarak yürütülmüştür. Denemede kullanılan çöp kompostu İzmir Büyükşehir Belediyesi Uzundere Kompost Fabrikasından temin edilmiştir. Deneme bölünmüş bloklar deneme planına göre, 7 kompost dozu (0, 2, 4, 8, 10, 12 ve 16 t/da), 3 tekerrürlü olarak yürütülmüştür. Kompost, fabrikadan alındığı haliyle kuru ağırlık üzerinden hesaplanarak parsellere uygulanmıştır. Parsellere kışlık arpa ekilmiş ve mineral gübre ilavesi yapılmadan hasada kadar doğal şartlarda bırakılmıştır. Hasattan sonra toprak örnekleri alınarak analizleri yapılmıştır. 2. yıl parsellere çöp kompostu veya herhangi bir gübre ilavesi yapılmadan sadece kışlık arpa ekilmiş ve hasat sonunda toprak örnekleri alınarak analizleri yapılmıştır. Alınan toprak örneklerinde her iki yılda da agregat stabilitesi, hidrolik iletkenlik, hacım ağırlığı, porozite, saturasyon %’si, tarla kapasitesi, solma noktası gibi toprakların fiziksel özellikleri analiz edilmiştir. Analiz sonuçlarına göre, katı atıklardan elde edilen çöp kompostu toprakların fiziksel özel likleri üzerine olumlu etkide bulunmuşlardır. Bu etki; hidrolik iletkenlik, hacim ağırlığı, saturasyon %’si ve tarla kapasitesi üzerine istatistiki olarak önemli iken agregat stabilitesi, solma noktası gibi özelliklere etkisi belirgin olmamıştır. Genel olarak parsellere verilen kompost dozu arttıkça kompostun toprak fiziksel özelliklerine etkis i daha belirgin olmuştur.
This two-year field study was conducted to investigate the effects of municipal solid waste compost on physical properties in Xerofluvent soils. The waste compost used in the study was obtained from Uzundere Compost Factory belong to Municipal of İzmir City. The study was carried according to split block e xperimental design with three replications and seven compost doses (0, 2, 4, 8, 10, 12 and 16 t/da). The amount of compost applications to the plots was calculated based on dry compost weight. Winter barley was sown in the plots and grown without any fertilization until the harvest. After harvesting, the soil samples were taken and analyzed. In the second year, the winter barley was sown in the same plot without any waste compost and mineral fertilizer. At the end of harvest, again soil samples were taken and analyzed. In the soil samples taken, in both years, some physical properties such as aggregate stability, hydraulic conductivity, bulk density, saturation percentage, field capacity, wilting point, were determined. According to the results of analyzes, waste compost obtained from solid residuals had a positive effect on physical properties of soils. This effect was significant on hydraulic conductivity, bulk density, saturation percentage and field capacity whereas it was not significant on aggregate stability, and wilting point. In generally, at the higher compost doses, the effect of compost on the physical properties of the soils was found to be more significant.
