AGRO 76-FitoMarche: A tool to assess pesticide vulnerability maps and to estimate pesticide leaching in a stochastic way
No full textThe use of models to predict the behavior of agrochemicals has been promoted in the EU directive 91/414. A new software package to draw pesticide vulnerability maps has been developed. The tool links ESRI ArcGIS 9 with MACRO 5.0 in standalone software called FitoMarche and uses ArcObjects libraries as a middle tier. FitoMarche is easy-to-use software that allows the user to simulate pesticide behavior at different scales, depending on the detail of the input data, because part of the scenario data is taken from shape files and the rest is stored in an internal database. The tool requires shape files to describe the simulation area, the soil the land use, the rotations, and the climate. Moreover FitoMarche can be used to assess the pesticide fate using a probabilistic approach. In this case, the shape file does not contain real data but a grid where each polygon is identified by a different identification code

Losses of atrazine, metolachlor, prosulfuron and triasulfuron in subsurface drain water. II. Simulation results
No full textThe MACRO model was applied to predicting the losses of atrazine, metolachlor and prosulfuron in subsurface drain water of two experimental fields located in the Po Valley, Cadriano and Carpi (Italy). For the entire simulation period (March 1996 to February 1997) MACRO was able to predict the drain flow of the two experimental sites (111 and 93% of the total measured drainage drain water, respectively, in Cadriano and Carpi). Atrazine and metolachlor losses via the drain were predicted at 46.8% to 29.9% in Cadriano and 45.3% to 20.9% in Carpi, respectively. The losses of prosulfuron were overestimated (200%) in Cadriano whereas they were underestimated (66.7%) in Carpi. The model simulated most of the drainage events but it failed at simulating the concentration of atrazine and metolachlor in the first drainage events after the herbicide application when the highest concentration of the study was observed. Mass losses in each event were clearly a function of the soil and herbicide properties and the model followed this trend well
