The trial aims to improve the protection and management of the soil, the well-being of the plant and the quality of production in the wine supply chain organic and biodynamic, using an innovative product “ZEOWINE” resulting from the composting of waste of the wine and zeolite supply chain. At present, the use of zeolites in agriculture is a fast-spreading practice; their application to soils (both as natural zeolites and in combination with organic and mineral fertilizers) not only increases production but also leads to the exaltation of quality indices. The research was conducted in the 2019 season in San Miniato (Tuscany) on the vineyard of Sangiovese in production, performing the following inter-row treatments at the beginning of January: commercial organic fertilizer, zeolite (clinopthylolite) and zeowine (combination zeolite and compost obtained through grape processing waste) in the respective doses of 20 t/ha, 10 t/ha and 30 t/ha. Following the treatment, we measured gas exchanges and water potential, berry weight, °Brix, pH, acidity, total and extractable anthocyanins and polyphenols. Treatments with Zeowine and zeolites reduced water stress. In Zeowine treatment, soluble solids were lower, while acidity, pH and berry weight do not vary from control. Statistical differences are also noted in the concentrations of anthocyanins and polyphenols. Results suggest a positive impact of Zeowine treatment on physiology and quality characteristics in V. vinifera.
