The Variation Content of Nutrients Mobile Forms in Vine Leaves under the Influence of Technological Links

Abstract. The research took place in a vineyard ecosystem from Bujoru’s Hills. Ecopedological conditions are favorable for viticulture, especially for red varieties. The soil is a cambic chernozem with degradation trends.The experiment followed the dynamics of macroelements and microelements under the influence of mineral and organic fertilization as well as under the influence of the mechanical and biological maintenance of the soil during two important phenophases: flourishment and fructification. The parallel analysis of the soil and the plant is the most effective way to determine the nutritional regime of the vine. They allow us to interfere directly in order to optimize nutritional regime so as to achieve maximum efficiency and high quality. The data obtained in the context of the Bujoru ecosystem revealed the existence of the soil-plant-production relations which are useful in developing a coordinated system of fertilization and the maintenance of an ecological design
