Nutrition in the grapevine is a specific agrotechnical measure affecting the quantity and quality of grape production and its products. Proper nutrition has a great influence on the many biochemical and physiological processes that happen in various grapevine organs. Among the macro-elements, potassium has a very important role in the development of the vital processes of the vine. This element has the most important influence on maturation processes and increases the resistance of the vine to low winter temperatures. Results achieved in a 2-year (2016-17) study with seven different pleural treatments (along with the control) showed that fertilization with K reduced Mg almost half compared to untreated vineyards, resulting in chlorosis in the basal leaves. High K / Mg Report, determining the low absorption of Mg, did not sit on our test as from leafy fertilization as from irrigation and fertilization both (injection with drop irrigation) with MgSO4 solution. On the other hand, the application of Mg except Fe supply had the same effect on the absorption of Zn soils and its accumulation in leaves and leaf tails. For more, foliar fertilization with Fe has increased Fe levels on leaves, on berry and on one measure smaller in ripening too.
