Sažetak
A one-dimensional Pesticide root zone model (PRZM) approximated by the method of lines and finite-differences that accounts for pesticide fate in the crop root zone is applied. PRZM model investigates effects of distribution of rainfall and water evapotranspiration, water convection and diffusion in soil as well as pesticide biodegradation within and immediately below the plant root zone. The model is given by coupled second order partial differential convection-dispersion equation and biodegradation with time-variable boundary conditions. Adsorption/desorption studies are very useful for providing essential information on the mobility of pesticides and their distribution in the soil, water and air. Adsorption data can also be used for comparative and modelling purposes. The objective of this research was to determine the parameters of non-linear adsorption isotherms (Freundlich, Langmuir and Temkin) for atrazine by fitting the adsorption experimental data to the isotherm models and implementation of Freundlich isotherm in PRZM model in order to simulate atrazine dissipation in the corn field from Slavonski Brod (Croatia).
