Methodological framework for characterizing vineyards subjected to soil degradation in Piedmont

The IN-GEST SOIL project aims to address soil degradation, particularly soil erosion by water, in hillslope vineyards in the Piedmont region of Italy. This study proposes a methodological framework for comprehensive vineyard characterization to establish a baseline for soil health investigations. The characterization involves using regional databases for climatic, geological, and pedological data, integrated through field surveys. Soil samples were collected to determine bulk density, granulometry, and organic matter content. The results indicate significant variability in geology, soil texture, organic matter content, and bulk density across different sites. Bulk density measurements revealed that soil compaction was close to or exceeded the threshold affecting root growth, particularly in the track position, where compressive effects from tractor wheels or tracks are concentrated. These findings highlight the need for site-specific soil management strategies to optimize vineyard productivity and sustainability. This preliminary study serves as a foundation for future research focused on long-term monitoring of soil management practices and their impact on vineyard sustainability and resilience in the face of climate change. Engaging local farmers and stakeholders in adopting sustainable practices is crucial. The choice of management strategies will be informed by data from this study and insights from a parallel study on winegrowers’ perceptions and behaviours.
