Description:	The start point for a reliable use of pesticide leaching models is to have an accurate description of the water flow. The pesticide leaching model PEARL uses the SWAP model to describe the water flow and has never been tested under Brazilian conditions. The aim of this work was to test and to calibrate the SWAP model to describe moisture profiles in a Brazilian very clayey typical dystroferric Red Latossol in Dourados, Mato Grosso do Sul State, Brazil. The SWAP model was tested in one experimental field of 0.09 ha cultivated with soybean and soil profiles were sampled eight times between December 2006 and October 2007. SWAP input values (i.e. soil water retention curves and meteorological data) were based on in-situ measurements. Simulations with the uncalibrated soil water retention curves resulted in moisture profiles that were too wet between 0-10 cm depth for all sampling dates. After calibration of water retention curves, there was a good improvement in the simulated moisture profiles that were within the range of measured values for almost all depths and sampling dates
