Application of nitrogen forms such as nitrate, urea, and amino acids effects on leaf and berry physiology and wine quality

São Joaquim (28º17’38 “S and 49º55’55” O) is a viticultural region located on the Santa Catarina Plateau, south region of Brazil, which is known for vineyards that produce fine wines from grapes cultivated at altitude (> 900 m). It is amongst the coldest (annual average of 13.42 ºC, 1832.36 hours of solar radiation and 1680.23 mm of precipitation) and the highest (715 – 1638 m) Brazilian’s viticultural regions, with hilly relief (43% of slopes between 20 – 45% of declivity, with no preferred direction).

A plant’s cuticle layer is an external waxy barrier to the lipid membrane and the plants first line of defense.

The Mediterranean region stands out as a “hot spot” due to projections of substantial increases in temperature and decreases in rainfall, which would lead to marked decreases in water availability throughout the Mediterranean region.

The Precision Viticulture (PV) is defined “as a management system that is information and technology based, is site specific and uses one or more of the following sources of data: soils, vigour, nutrients, pests, moisture, and yield among others, for optimum profitability, sustainability, and protection of the environment” (OIV, 2018, in process). The elements mentioned in the definition are an important part of the terroir components. The terroir is a tool In Viticulture, it is the analysis and study unit, and the variability of a certain situation can be due to any difference in every element or property of each factor that constitutes it, including the management.The soil and its management are those that bring the most variability to terroir.
