Nutrients and heavy metals in a vineyard soil under organic, biodynamic and conventional management

Trends already extended for more than 12 years show a decline in both consumption and international trade, particularly in volume. However, there are also positive signs in several categories of wine, segments and markets, as well as a better trend in terms of value. How are these trends affecting wine producers and distributors? Are they short or long term? do they mean radical and permanent changes to which a way of adaptation has to be found or are they just temporary changes that may only require some calm? How are companies adapting to these new trends? Which are their effects on wine regions?

Valbelluna valley is an area located in the northeastern Italy. It is extended from the East-West between Feltre and Belluno, along the Piave waterway and enclosed between Cansiglio valley on the South and the Dolomites in the North. Here, the villages of Limana and Trichiana are present, which are considered for decades potentially interesting areas to aim a niche production with own particular properties.The position of this area, its sun exposition, its soil composition and the microclimate, are ideal factors to obtain vines and consequently wines with unique features especially regarding the diversity and complexity aroma.

The use of hybrids in viticulture is one of the alternatives for sustainable production in hot and rainy regions during grapevine maturation. This sustainable production concerns the reduction of pesticide use, adaptation to climate and control of vine decline. The SR 0.501-17 wine grape hybrid, developed in the grapevine program of the Agronomic Institute of Campinas (IAC), is characterized by producing white grapes with small spherical berries with seeds. The agronomic characterization of this hybrid, especially in different climatic conditions, as well as the evaluation of its performance in winemaking are necessary. The objective of this work was to characterize the duration and thermal requirements of the different phenological stages and the influence of rainfall on the physicochemical characteristics of the must in two contrasting climate regions of the State of São Paulo.

In 1979 an enlightened and farsighted business owner in an area and in an activity unknown to him and in 120 hectares of land cultivated with corn and wheat expressed to one of us that he wanted to start a business in the wine sector. The first innovative “Vigna Dogarina Scientific Applicative Project” has become famous and harmoniously inserted in and with the “Territoir” of eastern Veneto in northeastern Italy. The revolutionary project allowed one of us: 1. to put into practice results of research related to the applied philosophy, vision, methodology of the “Great MetaEthic Chain 4.1C®” algorithm of the “Conegliano Campus 5.1C®” that considers all material, immaterial, spiritual, technical, economic, environmental, social, existential, relational, ethical, MetaEthical factors with basic indexing in a harmonious chain “ 4.1C®” and application “5.1C®”, 2. to implement:

There is an urgent need to develop protective measures for grapevines in historically significant dry-farming vineyards, particularly on Mediterranean islands.
