The use of geoadditive models is proposed to analyse the spatial distribution of the sodium absorption ratio (SAR) of a citrus groves cultivated area, in order to ascertain the factors influencing its extreme salinization. Geoadditive models are considered as an evolution of universal kriging, allowing explicit consideration of the linear and nonlinear relations with relevant explanatory variables as well as the spatial correlation described by a standard spatial autocorrelation function.

Abstract
The use of geoadditive models is proposed to analyse the spatial distribution of the sodium absorption ratio (SAR) of a citrus groves cultivated area, in order to ascertain the factors influencing its extreme salinization. Geoadditive models are considered as an evolution of universal kriging, allowing explicit consideration of the linear and nonlinear relations with relevant explanatory variables as well as the spatial correlation described by a standard spatial autocorrelation function.File in questo prodotto:
