EPIC Model Simulation of a Central-West Sardinia Traditional Cropping System

In the’80. EPIC model was developed in order to evaluate soil erosion and soil productivity relationship (Williams et al, 1984). Since its inception. EPIC has evolved into a comprehensive agroecosystem model for analysis of cropping systems and cultural practices on production, soil and water quality, water and wind erosion (Williams. 1995). Here we describe the calibration and the utilize of the EPIC model in Arborea (39° 47’ 44.2"N latitude and 8° 33’ 42.0"E longitude), a Central-West of Sardinia (Italy) area characterized by dairy cow breeding farms in a double cycle maize - annual ryegrass.
