    Abstract

    : In questo studio un modello geo-additivo e' stato utilizzato per analizzare la distribuzione spaziale del tasso di assorbimento del sodio nella zona costiera di Muravera-Villaputzu (CA) per individuare le cause che ne hanno determinato leccessivo grado di salinita', dannoso per le colture agrumicole praticate nella zona. I modelli geo-additivi rappresentano unevoluzione del kriging universale e consentono di considerare esplicitamente i legami non lineari tra la risposta e le covariate e la correlazione spaziale descritta mediante una funzione di autocorrelazione.
