Objectives
Within-field variability reduces the efficiency of traditional vineyard management. The Project aims to optimize economic performance of wineries from the Colli Piacentini wine district by promoting a larger use of proxy and remotely sensed data. Accordingly, precision viticulture protocols will be set up and promoted towards increased competitiveness, resource use and vineyard sustainability under a new climatic context.
Activities
The Project encompasses the following activities: a) impact assessment of winter cover crops site-specific sowing on temporal and spatial vineyard variability, vine performance and fruit composition; b) pesticide spray efficiency and drift monitoring as well as assessment of grapevine disease infections depending on traditional vs variable-rate spray application; c) characterization of fruit and wine composition (experimental and/or commercial) as related to vigor classes and harvest methods (selective vs traditional); d) result dissemination including field-based demonstrative activities.

3 Practice Abstracts
Development of reliable protocols for precision viticulture (PV) relies upon deep knowledge of the nature and extent of within-field variability. This study aimed to identify if and how soil-related factors may influence within-field heterogeneity under different pedological contexts. The experience was carried out in five vineyards sited in the Colli Piacentini wine district (Italy) where within-field variability was mapped by proximal sensing and three vigor zones identified. For each zone and vineyard, a soil characterization was made, and canopy growth, yield components, and fruit composition assessed. The results allowed the vineyards to be clustered into two groups: (i) Tidone Valley and (ii) Alluvial Terraces where spatial variability is mostly related to soil depth and topography, respectively. After defining the main drivers of variability, the second step is the definition of the best management approach related to the final aim. In case of temporal stability (first group), vineyard management could be based on the variable rate application of fertilizers, organic matter or cover crops towards an increased within-field homogeneity. In the second group, considering the substantial impact of water dynamics, variable rate irrigation might contribute to control water scarcity and reduce within-field variability. In both cases, selective harvesting is the easiest solution for managing existing variability to get product differentiation and increased revenues.
Adaptation of canopy sprays depending on actual vine vigor is a promising solution for increased sustainability. This is a priority element to cope with stringent restrictions on PPP use, increasing costs of agricultural chemical and organic agriculture needs. The study aimed to test the performance of an on-the-go system for variable canopy spray (VRA) and to optimize copper use. The trial was performed on a vertical shoot positioned (VSP) trellis using a commercial air-blast sprayer. Conventional spray (CT) and spray were compared over two seasons. Plant growth, yield components, downy mildew infections, leaf coverage, losses to the ground and adjacent rows were assessed. When compared to CT, VRA allowed 15-21% pesticide save, maintaining similar application efficiency in terms of canopy coverage and off-target losses. A traditional sprayer was adapted for real-time adjustment of canopy spray based on actual vigor assessed by proxy. The experiment demonstrated that the transition of agricultural systems to a more sustainable approach and to digitalization is possible thanks to the adaptation of already existing machines. This promotes digital transition also among smallholder farmers without imposing to buy new expensive machines and equipment. Winegrowers’ interest in the VRA of copper should be justified by the possibility to keep similar crop protection without affecting yield and fruit composition and reducing the use of PPP as compared to conventional spray.
Having identified the pedological and agronomic bases at the origin of the intra-parcel variability of the vineyard clearly visible in the vigour map, it becomes of fundamental importance to clarify which is the most appropriate way to manage such variability in order to avoid inefficiency, waste and increase of a negative environmental impact of viticulture. It is interesting to note how the most convenient strategy can in some cases be identified in solutions aimed at standardising the existing variability towards a condition of vigour considered optimal with respect to the prefixed oenological objectives or, in other cases, in exploiting the existing variability in order to increase the added value of the grapes through selective harvesting followed by process and product differentiation. This decision cannot be taken without a rigorous ground validation of the vigour maps, which makes it possible to associate each vigour class with the real physiological state of the plant and to identify the oenological potential of the grapes. On the basis of this operation, the most appropriate management plan can be developed for each vigour area (e.g. a differentiated fertilisation plan between areas of different vigour), converting the vigour map into a prescription map that will then be implemented when distributing inputs (e.g. fertiliser, seed, plant protection products) thanks to variable rate technologies. These maps, geo-referenced, will then be connected, through the most innovative mechatronic solutions, to an operating machine capable of adapting its operating intensity to the prescription map since it is equipped with technologies that can physically separate the riper harvest from the less ripe harvest in two separate hoppers.
