Abstract |
The development and testing of a mathematical model to simulate the loss of pesticides from agricultural lands are presented. The Pesticide Transport and Runoff (PTR) Model is composed of submodels concerned with hydrology, sediment loss, pesticide-soil interaction, and pesticide attenuation functions. The Model 'piggybacks' the applied pesticide onto the movement of water through the soil profile and the loss of water and sediment from the land surface. The pesticide-soil interaction is based on the Freundlich adsorption-desorption isotherm. Comparison of simulated and recorded runoff and sediment loss showed considerable agreement.
