Includes bibliographical references. "The Root Zone Water Quality Model (RZWQM) developed by the U.S. Agriculture Research Service was evaluated for subsurface drain volumes and nitrate concentrations in the drain flow in an experimental plot under free drainage management. The results of the evaluation demonstrated that RZWQM can simulate physical and chemical processes in the root zone of crops. The results of the evaluation of the model are reported here. The biological component of the model was not evaluated at this time"--Management perspective. Includes management perspective and abstract in French. gccst Fertilizers Ng, H. Y. F., author. Tan, C.
