Sažetak
In the coastal and island parts of the Republic of Croatia, significant karst surfaces are covered with degraded macaque and poor forest vegetation. Such soils represent potential for cultivation and amelioration, in order to plant vineyards. Karst cultivation implies demanding procedures for the preparation of soil suitable for the cultivation of agricultural crops, such as cleaning and removing forest vegetation, leveling, ripening or squeezing, grinding, milling and grinding of stone. Karst soil is a soil dominated by sedimentary rocks - mostly limestone and less frequent dolomites, salts and gypsum - which are subject to mechanical and chemical erosion. For the purposes of studying the agrochemical properties of ameliorated karst soils, soil samples were taken from production vineyards (locations where amelioration was carried out in 2008- 2009), in three different locations; Istria County (location near Rovinj), Zadar County (location Ravni kotari) and Split-Dalmatia County (location on island Brač). Two average soil samples were taken at each site on two depths, 0-30 cm and 30-60 cm, about 1.0-1.5 kg of soil and milling stone fraction (after separating the stone fraction with diameter of 25 mm or more, from the individual soil samples). The biggest problem that can be noticed after 10 years after amelioration is the evident high levels of carbonate (CaCO3), elevated pH values (pH>7.0) and very low levels of available phosphorus and iron in the soil. From the point of view of fertilization of grapevine, and other fruit cultures in ameliorated karst soils, it is necessary to find effective and applicable solutions to these problems which negatively affect soil fertility.
