The aim of the paper was to used of three types of mathematical function: the single first-order degradation kinetics (SFO), Gustafson and Holden model (FOMC) and the simple linear bi-phase model, for quantification of the fate of pesticides in soil. For instance data from laboratory study of dissipation of atrazine in soil was used. Numerical methods using for estimate of structural coefficients of degradation models of this herbicide. For every models assessed the values of 50, 90 and 100% dissipation time of substance active. Mathematical equations and figures of first derivative of functions were presented as the analysis of atrazine degradation process. Accomplishment of estimate adequately of using models. To the last degree of the kinetics criterions of degradation of substance active and the statistics criterions make good the Gustafson and Holden model. In this work find that analysis of degradation rate is valuable of study integration of kinetics degradation herbicides in soil.
