61 Symposium--In-Season Nutrient Management

Oral Session
ASA Section: Agronomic Production Systems This symposium is an extension of the Nitrogen Uptake Efficiency workshops that have been held annually in various Midwest locations since 2003. Attendees (45-120) were largely regional and include graduate students that reported their observations and experiences as the sensor technologies were developed and protocols for their use were proposed. Three sensors have now been commercialized and some results have been published. The intent of the symposium is to provide a way for potential users and curious individuals to easily become familiar with how the sensors might be used for various applications. These technologies and associated applications have a high potential to improve environmental quality, especially in situations where animal wastes are applied to cropland and where precipitation is highly variable.
