Abstract

[automatically translated] INTRODUCTION Those who work in the field of agriculture, and more specifically in viticulture, has seen time in the evolution of the production goals and, therefore, the way to manage the vineyard, going from maximizing productivity to the "lowest cost", the maximization of quality "at all costs ", until you get to a view of the vineyard system as an entity included in the environment (in the broadest sense) and not just home to a productive purpose and able to deliver tangible and intangible assets. The conceptual shift: "production order" - "multipurpose end," is expressed in the term "sustainability." The latter is often confused and abused, it carries with it an inherent and additional meaning, represented by the stimulus to agricultural management towards future generations. Enshrine the goal of "sustainable production" means going into the details of this variability in the field. Only by varying margins intervention it is possible to condense the optimization of management with the protection of the environment and, given the technological level and the availability of the same, it becomes an unjustifiable use of instruments of precision viticulture. Operate on the variability of the vineyard, which can be pushed up to the variability present in the single plant, creates the preconditions to enter the agronomic management a great deal of information that is otherwise difficult to reach and quantifiable. Be able to represent with a simple histogram of the frequencies of a vegetation index throughout the variability present in the area, in addition to an objective value, condenses into whether the effectiveness of the implemented agricultural techniques, the mistakes, the environment cultivation and expression of the productive potential it expressible. The approach of precision viticulture that relates to an anthropic complex system which is precisely the vineyard, is also complex and based on the use of satellite positioning technologies, now with the order of centimeters error, on geographic information systems, on the remote acquisition instruments, proximity, contact which lead optical technologies, radiometric. All instruments with a high technological value but in need of specialized support and at the same time "holistic" agronomist. It is the key figure for the translation of optical information, radiometric, in applicable agronomic information. The transition from vegetation indices to a simple variable agronomic such as the amount of fertilizer used in variable rate in the parcel, regardless of the estimation method of the same, should prompt the agronomist from the establishment or study of "directions for use "compared to the variable mapped enriched from the experience and, equally important aspect, the real vision state of the vineyard in which it must operate. All these aspects, they release the agronomist, the sterile formulation "at the table" agronomic intervention, stimulate him to check the field and looking for more in-depth analysis of targeted than the identified variable. In this framework, the themes of precision viticulture that were addressed by the wine-growing research for about twenty years was concluded with the experiences of applications in the image of the vineyard management process multispectral acquired by satellite in early 2000. The issues addressed in the field of research from the University of Palermo and Milan, they are long since applied in the operational field. The purpose of this manual is therefore to condense, so certainly not limited to, the activities
