Use of Sentinel-2 Satellite for Spatially Variable Rate Fertiliser Management in a Sicilian Vineyard

Satellites can be used for producing maps of within-field crop and soil parameters and, consequentially, spatially variable rate input application maps. The plant vegetative vigour index (i.e., Normalised Difference Vegetation Index—NDVI) the leaf water content Water Index—NDWI) were to study—through both time space—the phenological phases two plots, with Syrah Nero d’Avola grapevine varieties, in a Sicilian vineyard farm, located Naro (Agrigento, Sicily, Italy). aim this work is produce nitrogen fertiliser applied plots under study as well understand when they should fertilised or not according their target yields. average showed high temporal spatial variability during all these results, optimal fertilisation have been 12 April 2021. In fact, operation aimed at supporting activity but must performed therefore, are high. Therefore, around 2021 using previous NDVI taking into consideration management zones. This demonstrates usefulness remote sensing data Decision Support Systems (DSS) order reduce production cost, environmental impact climate footprints per kg produced grapes, European Green Deal challenges.
