CMIS Educational Model

The model predicts movement of pesticides through soils using weather and irrigation provided on a daily basis. The applet displays two soils side by side so comparisons can be made between different soils, chemicals, irrigation systems, and several other parameters. Soil and chemical properties along with cumulative infiltration amounts can be viewed on the output screen. The simplified model incorporates mass flow, dispersion, sorption, and degradation.

The split-screen display was developed as an educational tool by Art Hornsby and Ron Jessup at the University of Florida. It was originally written in Basic and distributed on diskette with teaching materials for use in secondary schools. Soil, chemical, and weather data used in the model can be easily modified for different locations.
