Sustainability Report FY 2021

71 RUFFINO | Sustainability Report FY 2021 excellent bio-indicators to assess the quality of surface freshwater; • Lichen Biodiversity Index (IBL-bf) analyzes the lichen epiphyte communities that are a valid indicator of air quality. The Association’s experts have visited our soil every year since 2018 to verify the indices and, more broadly, the quality of the land that we ma- nage. The products that can use the “Biodiversity Friend” certification are currently: • Riserva Ducale Oro Chianti Classico Gran Selezione DOCG • Greppone Mazzi Brunello di Montalcino DOCG • Alauda IGT Toscana • Fiasco Chianti Superiore DOCG • La Solatia Pinot Grigio IGT Toscana • Romitorio di Santedame Chianti Classico Gran Selezione DOCG • Santedame Chianti Classico DOCG • Prosecco DOC • Prosecco Rosé DOC • Pinot Grigio Delle Venezie Integrated production To support the path taken and contribute to the preservation and defense of the values of nature, we retain that it is important to obtain certifica- tion that attests to our compliance with the In- tegrated Production Guidelines and, in FY 2021, all our companies have been certified with the standard “Sistema di Qualità Nazionale di Pro- duzione Integrata” (SQNPI). The standard SQNPI is a voluntary certification scheme that attests to the use of integrated pro- duction techniques that includes the application of specific regulations for each crop, agronomic practices and binding phytosanitary indications (stated in the production guidelines) both in the choice of phytosanitary products and in the pos- sible number of treatments. Management practi- ces are the strictest and the choice of usable phytosanitary products is greatly reduced com- pared to the practices and products whose use is permitted in the Integrated Production not certi- fied by the SQNPI standard. In line with the choice to reduce the use of che- mical products to prevent and treat disease in the vineyard, we also avail of advanced forecasting models that process data from meteorological and environmental wireless sensors in weather stations on the estates. In particular, by analy- zing precise data about parameters such as tem- perature, air humidity, rainfall, leaf wetness and wind speed, and knowledge of the phenolic stage of the vines, a more precise and balanced defense against disease is possible with a lower impact on the environment. This data analysis is helped by the use of a De- cision-making Support System (DSS), which is instrumental for gathering, organizing and integrating information about the weather and the vineyard environment. Due to mathematical models, the system interprets the information available and, by comparing it with parameters set out by experts, it provides decision-making support and alerts in order to make informed de- cisions regarding vineyard management. In order to ensure traceability of the chemical products used, whether it is manure or pesticides, since FY 2013 the estates have used Quaderno di Campagna (QdC) management software, which is connected to the ministry’s chemical products database. The software enables the automatic ve- rification of the correct dosage and signals any faults, as well as monitoring final warehouse stock in compliance with the law.
