Sažetak
Wine growing area of Croatia is divided in the continental and litoral region. Each region is divided into sub-regions, wine growing areas and wine growing positions. Since 2003-2011 soil sampling (two depths: 0-30 / 30-60cm) from 2945 ha of vineyards situated in Eastern Croatia (Slavonija and Podunavlje sub-regions, Srijem, Baranja and Erdut wine growing areas) have been made with aim of testing main agrochemical characteristics including status of plant availabe phosphorus (P) and potassium (K) determined by the AL-method. By this study has been covered 60% of vineyard areas of four counties of the region as follows: Osijek- Barannya, Vukovar-Syrmium , Virovitica-Podravina. and Brod-Posavina. In general, 33% of tested area were poor in AL-soluble P and K in the surface soil layer (<12 mg P2O5/100 g and < 19 mg K2O/100g). However, in the deeper soil layer 55% and 59% of the tested area were in this category of availabilities of P and K, respectively. Also, 33% and 12% of tested soil area (0-30cm depth) were rich in P and K (>20.1 mg P2O5/100 g and > 30.1 mg K2O/100g). Based on this investigation soil K status in vineyards of the region is less favorable for grapevine growing compared to P status, mainly because of considerably lower contribution of rich K soil. Fertilization of vineyards with correspondingly amounts of P and K fertilizers based on soil test results, are needed for additional increases of grapevine yields and quality under conditions of Eastern Croatia.
