The research focused on the analysis of the impact of these macroelements, used in different doses and ratios, on the accumulations in the plant and on the production quality, respectively on the varied acidity of Fetească albă must. The analysed Fetească albă variety is one of the predominant varieties of the Sorogari wine-growing center, belonging to the Iasi vineyard. The soils of the area under study are part of the group of anthropogenic soils, such as cambic cherno-zones, forest ash and regosols, with uneven fertility. Values of the content in the plant of 2. 2% N, 0. 83% P, 0.883 K as well as acidity values of 5.27 g/l H2SO4, by applying fertilizers in the minimum necessary doses, certify that they can be at the level statistical assurances It can be stated that the use of doses of fertilizers according to the criterion of sufficiency, in the analysed agro-eco-pedological context, ensures that the optimal experimental doses, optimal contents in the plant of macronutrients and implicitly, the nutrition environment is protected from pollution.
