Introduction: Business Meetings: Sensor-Based Nutrient Management Community Wednesday, October 24 th 4:00 pm – 4:30 pm Duke Energy Convention Center, Room 263, Level 2 Division S4/S8 Joint Business Meeting Tuesday, October 23 rd 4:00 pm – 5:00 pm Duke Energy Convention Center, Room 200, Level 2 This community focuses on applications of sensor- based technologies including field studies that cover interpretation of sensor data, nutrient recommendations, and use of sensors to assess crop vigor in general. Unique applications that are linked to other production considerations are encouraged, as are experiences from producer fields. Sensor-Based Nutrient Management Community 2012 Chair: James S. Schepers Community Activities: Published Literature: 2011 ASA In-Season Nutrient Management Symposium 2012 Precision Agriculture Conference in Indianapolis, IN Poster Competition: The Sensor-Based Nutrient Management Community is sponsoring a graduate student poster competition. The posters being evaluated are in Division C3 section 100, Division S4 section 133, and Division S8 section 152. Members of this community publish in several journals.
