The USDA/ARS Root-Zone-Water-Quality-Model (RZWQM) is a multi-modular physically-based model that simulates the many processes in the soil-crop- atmosphere continuum on a daily basis. The study evaluates the potential of the RZWQM to simulate a typical center pivot irrigated corn production system in Eastern Colorado. At the evaluation site, the coarse textured soils having low water holding capacities, require frequent irrigation which increases the potential for deep percolation of water and solutes below the root zone. Minimizing deep percolation of irrigation water increases nitrogen use efficiency and decreases water quality degradation from nitrates. Predicted values were compared with measured values for one growing season to parameterize the model. In the following year, deviations of the parameterized model's predictions from independently measured values for the 7 performance criteria ranged from 5-22%, indicating acceptable model performance.
