             abstract = "The water balance in agricultural cropping systems is dependent on 
                         the physical and hydraulic characteristics of the soil and the 
                         type of farming, both of which are sensitive to the soil 
                         management. Most models that describe the interaction between the 
                         surface and the atmosphere do not efficiently represent the 
                         physical differences across different soil management areas. In 
                         this study, the authors analyzed the dynamics of the water 
                         exchange in the agricultural version of the Integrated Biosphere 
                         Simulator (IBIS) model (Agro-IBIS) in the presence of different 
                         physical soil properties because of the different long-term soil 
                         management systems. The experimental soil properties were obtained 
                         from two management systems, no tillage (NT) and conventional 
                         tillage (CT) in a long-term experiment in southern Brazil in the 
                         soybean growing season of 2009/10. To simulate NT management, this 
                         study modified the top soil layer in the model to represent the 
                         residual layer. Moreover, a mathematical adjustment to the 
                         computation of leaf area index (LAI) is suggested to obtain a 
                         better representation of the grain fill to the physiological 
                         maturity period. The water exchange dynamics simulated using 
                         Agro-IBIS were compared against experimental data collected from 
                         both tillage systems. The results show that the model well 
                         represented the water dynamics in the soil and the 
                         evapotranspiration (ET) in both management systems, in particular 
                         during the wet periods. Better results were found for the 
                         conventional tillage management system for the water balance. 
                         However, with the incorporation of a residual layer and soil 
                         properties in NT, the model improved the estimation of 
                         evapotranspiration by 6%. The ability of the Agro-IBIS model to 
                         estimate ET indicates its potential application in future climate 
                         scenarios.",
