Delineation of site-specific management units in a saline region at the Venice Lagoon margin, Italy, using soil reflectance and apparent electrical conductivity
The study site is characterized by contrasting soils, presence of peat, and saltwater intrusion. About 53% of the spatial variability of maize yield was due to changes in soil properties. Apparent electrical conductivity (ECa) and bare-soil NDVI described soil spatial variability. ECa and bare-soil NDVI were used to delineate homogenous management units. The management units showed significant differences in yield and soil properties.
