Zoning like base instrument for the agronomist’s work in vineyard

Abstract

Ad una prima analisi l’interesse dimostrato dal settore produttivo nei confronti della zonazione vitivinicola è da ricondursi al fatto che dopo i primi approcci puramente accademici, la zonazione è diventata un fondamentale strumento operativo. Questo è avvenuto allorquando, in tali progetti è entrato a far parte del gruppo di lavoro, assumendo altresì un ruolo strategico, anche il fruitore del lavoro stesso e cioè il tecnico, colui che trasferisce in campo le informazioni prodotte e le applica nell’attività giornaliera.
Ecco quindi che il gruppo di lavoro già articolato e complesso per sua natura si è arricchito di una nuova figura che ha portato due grandi benefici.
Il primo luogo è stata introdotta nella filosofia del progetto una logica puramente operativa ed applicativa delle informazioni prodotte dal progetto cercando di tradurre la grande massa di informazioni prodotte in elementi utili e pratici, prontamente travasabili alla realtà produttiva. Secondariamente vi è stato un avvicinamento fra due mondi distanti. L’uno, il viticoltore per sua natura scettico nei confronti della ricerca viticola e delle innovazioni, l’altro, la ricerca scientifica che spesso rischia di perdere il legame con la base produttiva e le sue esigenze.
Agli inizi degli anni Novanta, l’Unità Operativa di Pedoclimatologia dell’Istituto Agrario di San Michele all’Adige (Tn) ha proposto, un modello innovativo che ha previsto in primis il coinvolgimento diretto e fattivo del destinatario della zonazione, rendendolo partecipe non solo in qualità di co-finanziatore dell’opera, ma investendolo di responsabilità tecnica e strategica prima, durante e dopo la realizzazione del progetto. I
Esempio di questa filosofia di lavoro è la zonazione delle Valli di Cembra e dell’Adige la cui pubblicazione successiva (Falcetti et al.1998) ha dato un chiaro segno di quelle che sono le potenzialità di un siffatto progetto; ha dimostrato come la conoscenza del territorio di produzione diventi uno strumento decisionale indispensabile per chi si trova nella necessità di gestire la vigna in modo razionale e finalizzato ad un preciso obiettivo enologico.
Dopo questo primo progetto che ha indicato una nuova strada metodologica da percorrere, numerosi sono stati in Italia i lavori improntati secondo tale modus operandi con il chiaro intento di fornire delle semplici indicazioni tecniche ai viticoltori ed ai tecnici operanti in una data area viticola (Fiorini et Failla, 1998; Colugnati et al, 1998, De Biasi et al, 1999).
Testimonianza della positività dei risultati ottenuti e della crescita di consapevolezza del settore verso tali progetti è il fatto che, se inizialmente furono gli Istituti di Ricerca a promuovere le zonazioni, ora sono le aziende che le commissionano.
Scopo del presente contributo è non aggiungere nulla di nuovo sulle metodiche scientifiche che stanno alla base della zonazione, ma presentare la testimonianza concreta di chi si trova ad affrontare in vigna una serie di scelte importanti e che dalla zonazione riceve supporto tecnico importante al processo decisionale operativo di campo.
Si proporranno alcuni casi di processo decisionale di campo supportato dai dati della zonazione adeguatamente trattati, gestiti e proposti attraverso lo strumento informatico specifico, noto come Sistema Informativo Territoriale o G.I.S. (Geographic Information System).

Influence of agronomic practices in soil water content in mid-mountain vineyards

In the context of LIFE project MIDMACC (LIFE18 CCA/ES/001099), several pilots have been installed in vineyards in mid mountain areas of Catalonia (NE Spain) to test well stablished agronomic practices to increase the adaptation of Mediterranean mid mountain to climate change. Soil water content (SWC) at three different depths (15, 30 and 45cm) was measured in continuum from August 2020. One pilot (WC) included a well-established green cover (GC), a new GC (NC) and a conventional soil management (CM, tilling+herbicides). NC presented an intermediate state between WC and CM, responding similarly to CM in autumn but quickly reaching similar SWC to WC, then following the same evolution till next spring, with CM presenting lower values along autumn and winter. Then vegetation activation decreased SWC in all plots, (much slower in CM, lacking GC). Sensibility to spring rains is again intermediate for NC, which joins SWC evolution of CM by the end of spring till next autumn. It is expected that NC will resemble WC more and more as its GC develops. In the pilot combining vine training (VSP vs Gobelet) and hillside management (slope vs terrace), no clear pattern could be related with these conditions. However, both terraces seem to be more sensitive to spring rains. A third pilot included new vineyards (7 and 1 year old). In the new vineyard (N), higher canopy development, a spontaneous green cover and row straw resulted in a slower SWC dynamic, not so sensitive to rains but conserving more soil water in spring and most of summer, even with presumably a higher water extraction by vines. In the newest vineyard (VN) the deepest sensor is still sensitive to rain events all over the year and SWC is always highest at this depth, revealing small water capture by vines.

Impact of climate change on the viticultural climate of the Protected Designation of Origin “Jumilla” (SE Spain)

Protected Designation of Origin “Jumilla” (PDO Jumilla) is located in the Spanish provinces of Albacete and Murcia, in the South-eastern part of the Iberian Peninsula, where most of the models predict a severe impact of climate change in next decades. PDO Jumilla covers an area of 247,054 hectares, of which more than 22,000 hectares

Local ancient grapevine cultivars to face future viticulture

Among the different strategies to cope with the negative impacts of climate change on viticulture, the exploitation of genetic diversity is one of the most promising to adapt to new conditions and maintain wine production and quality. One of the biggest concerns in the context of climate change is to improve water use efficiency (WUE). In this way, the use of genotypes that present a better response to drought and high WUE is a key issue. In this work, physiological performance analysis was conducted to compare the water deficit stress (WDS) responses of local and widespread grapevines cultivars. Leaf gas exchange, water use efficiency (WUE) at different levels (leaf and long-term WUE (∆13C)), leaf osmotic adjustment and other water relations parameters were determined in plants under well-watered and WDS conditions alongside assessment of the levels of foliar hormones concentrations. Results denote that local cultivars displayed better physiological performance under WDS as compared to the widely-distributed ones. he results corroborate the hypothesis that better stomatal control allows increasing leaf WUE under drought as occurred in the local Callet cv.; but the minority local cultivar Escursac cv. showed high WUE under both treatments. In this case, high WUE can be related to maintaining higher photosynthetic activity under drought. The different mechanisms underlying the better performance under WDS and high WUE of minority local cultivars are discussed.

Phenolic composition of Tempranillo Blanco grapes changes after foliar application of urea

Our research aimed to determine the effect and efficiency of foliar application of urea on the phenolic composition of Tempranillo Blanco grapes. The field experiment was carried out in 2019 and 2020 seasons and the plot was located in D.O.Ca Rioja (North of Spain). The vineyard was Vitis vinifera L. Tempranillo Blanco and grafted on Richter-110 rootstock. The treatments were control (C), whose plants were sprayed with water and three doses of urea: plants were sprayed with urea 3 kg N/ha (U3), 6 kg N/ha (U6) and 9 kg N/ha (U9). The applications were performed in two phenological stages, pre-veraison (Pre) and veraison (Ver). Also, each of the treatments was repeated one week later. Control and treatments were performed in triplicate and arranged in a randomised block design. Grapes were harvested at optimum ripening stage. High-performance liquid chromatography was used to analyse the phenolic composition of the grapes. Finally, the results obtained from the analytical determinations – flavonols, flavanols and non-flavonoid (hydroxybenzoic acids, hydroxycinnamic acids and stilbenes) – were studied statistically by analysis of variance. The results showed that, in 2019, U6-Pre and U9-Pre treatments increased the hydroxybenzoic acid content in grapes, and also all foliar treatments applied at Pre enhanced the stilbene concentration. Moreover, U3-Ver was the only treatment that rose flavonol and stilbene contents in the Tempranillo Blanco grapes. In 2020, all treatments applied at Pre enhanced the flavonol concentration in grapes. Furthermore, U3-Pre and U9-Pre treatments increased stilbene content in grapes. Nevertheless, the hydroxybenzoic acid content was improved by U6-Ver and U9-Ver and besides, hydroxycinnamic acid concentration in grapes was increased by all treatments applied at Ver. In conclusion, the lower and highest dose of urea (U3 and U9), applied at pre-veraison, were the best treatments to improve the Tempranillo Blanco grape phenolic composition.

‘Cabernet Sauvignon’ (Vitis vinifera L.) berry skin flavonol and anthocyanin composition is affected by trellis systems and applied water amounts

Trellis systems are selected in wine grape vineyards to mainly maximize vineyard yield and maintain berry quality. This study was conducted in 2020 and 2021 to evaluate six commonly utilized trellis systems including a vertical shoot positioning (VSP), two relaxed VSPs (VSP60 and VSP80), a single high wire (SH), a high quadrilateral (HQ), and a guyot (GY), combined with three levels of irrigation regimes based on different crop evapotranspiration (ETc) replacements, including a 25% ETc, 50% ETc, and 100% ETc. The results indicated SH yielded the most fruits and accumulated the most total soluble solids (TSS) at harvest in 2020, however, it showed the lowest TSS in the second season. In 2020, SH and HQ showed higher concentrations in most of the anthocyanin derivatives compared to the VSPs. Similar comparisons were noticed in 2021 as well. SH and HQ also accumulated more flavonols in both years compared to other trellis systems. Overall, this study provides information on the efficacy of trellis systems on grapevine yield and berry flavonoid accumulation in a currently warming climate.
