Autor: Porqueddu, Claudio, Caredda, Salvatore, Sulas, Leonardo, Farina, Roberta, Fara, Gianfranco

Four crops, common in the cultivation systems ofthe Sardinian hilly areas, were compared on a 30% slope and sandy loam texture soil during the period 1994-97 (i.e. natural pasture, improved pasture, annual forage crop and winter cereal). Rainfall, so

Modellizzazione della lisciviazione dei nitrati: calibrazione e validazione del modello LEACHN in diversi suoli e colture foraggere

Autor: Acutis, Marco, Argenti, Giovanni, Caredda, Salvatore, Cavallero, Andrea, Ducco, Giorgio, Fara, Gianfranco, Grignani, Carlo, Giordani, Cesare, Pardini, Andrea, Porqueddu, Claudio, Reyneri, Amedeo, Sulas, Leonardo, Talamucci, Paolo, Tarello, Cristina, Zanchi, Camillo

The LEACHN model calibration and validation was realized in three Italian enviroments (Piedmont, Tuscany and Sardinia), using nitrate losses by drainage from 4 soil types ranging from sandy-loam to day-loam. A set of large drainage lysimeters were us
