Abstract	Nowadays, there is an increasing interest in environmental friendly growing systems and attention has also been paid to the environmental impacts of fertilizations. Most frequented environmentally-benign fruit production systems is the organic system. Numerous studies have published about phytotechnique and plant protection of organic growing but considerably less information is available about the soil, leaf nutrient status and fruit quality of organic apple orchards. In this study, the nutrient status of apple cultivars in organic production system was investigated to establish the nutritional conditions of ecological fruit growing. Soil, leaf and fruit analysis was used to realize the effect of this environmental sound production system on environment and fruit quality.
