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 crop input application maps. The plant vegetative vigour index (i.e., Normalised Difference Vegetation IndexNDVI) a[...]![]()
