Phosphorus and potassium fertilizers are applied separately, after cleaning the weeds from the terrain. In order to achieve better homogenization of phosphate fertilizers with soil, it is recommended calculated in Table 1 fertilizer rates to be divided in two and to be applied twice. After fertilization, the area is ploughed at 15 cm in order to achieve better mixing of fertilizer with the soil. First three years after establishment of vineyard phosphorus and potassium fertilizers are not applied. During vegetation of vine is recommended to perform three or four times foliar fertilization with appropriate fertilizers, containing micronutrients and amino acids. Spraying of fertilizers can be combined with the performance of vineyard crop protection. CONCLUSIONS Advantages of this statistical method in the proposed model for geospatialization are that as a result of its application it is possible to outline sub-parcels for differentiated fertilization, with a proper from technological standpoint configuration.
