Özet

The objective of this study carried out at the Solar Energy Institute in Ege University, Izmir, was to investigate utilization of anaerobically digested cattle slurry combined with natural zeolite for rapeseed production. "Bristol" winter rapeseed cultivar was used as plant material in this study and the value of slurry as fertilizer for growing rapeseed was compared with commercial fertilizers. The anaerobically digested slurry may not be a suitable soil improver in its basic form owing to its viscosity. Therefore, further treatment can be essential to enhance its applicability as a crop fertilizer before use as an acceptable saleable product. In this study, natural zeolite as a bulking agent for improving quality of anaerobically digested cattle slurry was also applied to soil and found to have a beneficial effect on the characteristics of the end product. It was obtained positive results on plant growth and yield components of rapeseed by the addition of clinoptilolite to anaerobically digested cattle slurry.
