dc.description.abstractIn this paper, Opus, an agricultural contaminant transport model, was used to simulate a year of soil water flow and nitrate transport as well as crop growth for an arable cultivated soil, near Grenoble, France. This study is explicitly related to the cultivation of irrigated maize, a major crop in the area. The results have shown that, in terms of water balance, the simulations of water flow match the general measured trends. Drainage and evapotranspiration were estimated with errors of 4 and 20%, respectively. Runoff estimation was exactly accurate. Nitrogen movement and nitrogen concentration in the root zone were simulated well, and the cumulative leach beyond the root zone was estimated with an error less than 11%. The results for crop growth were good. Some reasons for these results are discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
