Aggelopoulou, D. Pateras, S. Fountas, T. Gemtos, G. Nanos] In the present study, the spatial variability of some soil physical and chemical properties in a 0.8ha apple orchard were studied. Sixty soil samples were taken from two sampling depths: 0-0.3m and 0.3-0.6m. The soil samples were analyzed for the following soil properties: soil texture, pH, cation exchange capacity and NO3-N, NH4-N, P, K, Na, Ca, Mg, Fe, Zn, Mn, Cu, B and organic matter content. Data analysis indicated that most of the nutrients were at sufficient levels. The site-specific application map for N was created based on the amount of N that was removed from the soil with the yield of the previous year. By applying N site-specifically, 38% of N could be saved compared to uniform application.
