Soil productivity determination and fertilizer recommendations in Croatia and Hungary

Computer models for fertilizer recommendation used in Croatia and Hungary are created regarding to soil properties, agroecological conditions and most frequent crops. Development of special profiles of agriculture have been generated need for more adjusted and more specific computer models. Basic models include soil chemical properties as pH, P, K and humus content as essential data. The importance of additional analyses and data (describing soil elasticity, heavy metals) depends on crops and soil properties. The aim of this paper was to describe procedures of models used in Croatia and Hungary for fertilizer recommendation and to describe model specificity regarding to special profile of agriculture.
