This tool supports user access of the HarvestChoice crop modeling results database for specific locations. Droppr returns a graphical display of the mean monthly rainfall for the selected location and allows the user to query the crop modeling results for specific baseline and improved (with intervention) production system scenarios. In this version of the tool, scenarios are specified in terms of crop, cultivar, planting month and nitrogen rates. Once the scenario specifications are submitted, a graphic of the baseline and improved yield levels are displayed for each year of the simulation.
