The research was carried out during the wine year 2021-2023 in the nursery viticultural Research and Development Stations for Viticulture and Winemaking Drăgășani. The object of study of this work is the influence of soil resources on the development of the root system and the aerial part of vine cuttings on the alluviceutricombosol soil type. Although culture technologies are still perfectible, they must be constantly adapted due to the continuous dynamics of this sector of activity, which must always be related to climatic conditions, economic and social situation. In this regard, research in the field was numerous and focused on aspects that were priorities at the time.All vine grape cultivars have a very high production potential, which in current conditions and with classical technologies is very little transposed into the yields obtained. The loss of nutrients from the soil through their absorption into the plant, through leaching through various agricultural works or other processes related to the natural dynamics of soils, entail the gradual decline of soil production capacity. It is necessary to compensate by applying mineral and organic fertilisers. The prolonged application of exaggerated doses of fertilizers or unbalanced combinations of chemical fertilizers with nitrogen, phosphorus and potassium often leads to nutritional deficiencies or physiological imbalances in the vine.
