Composts, which are prepared by using organic wastes in an aerobic environment, are widely used in organic agriculture to ameliorate soil structure in agriculture and support plant-feeding element content. Hazelnut and rice cultivation is commonly practiced in the province Samsun in the Black Sea Region. Every year, a large amount of wastes of these products have dumped into environment. So, this study has intended to determine opportunities of use of hazelnut husk and rice hull composts in organic strawberry cultivation and their effects on productivity and fruit quality. This research was conducted on the OMU’s Faculty of Agriculture Research and Application garden in Samsun between 2009 and 2011. In the experiment, impacts of different organic wastes such as hazelnut husk (H), hazelnut husk compost (HC), rice hull (R), rice hull compost (RC) and farmyard manure on mineral element contents of strawberry cultivars “Redline Hope” and “Fern” were investigated. Harvesting of plants were performed at the beginning of resting, fluorescence and at the end of harvest during the experiment in order to examine impacts of organic wastes on mineral element contents and N, P, K, Ca, Mg, Fe, Zn and Mn contents were detected in leaf samples extracted from these harvests
