2024 Abstract: A WEB-TOOL TO INFORM MID-SEASON CORN NITROGEN MANAGEMENT USING DRONES: Technology adoption through precision agriculture can help improve scouting efficiency, and ultimately optimize crop management. Previous research demonstrated that canopy greenness measured using inexpensive drones and the Dark Green Color Index (DGCI) can be used to assess mid-season corn nitrogen status. Calibration equations were created to compare mid-season field DGCI values to that of a nearby high-nitrogen reference and predict yield loss from nitrogen deficiencies. A web-tool was developed to simplify the process and make results available to producers, crop consultants, and county extension agents. Tool functionalities will be demonstrated as part of this presentation.
