InfoAg 2017 Presentation
 
 

Crop nitrogen need is directly related to yield potential and increases with higher production.  Spatial variation in crop yield across fields is well known and new technologies that allow on-the-go changes to plant population and even hybrid provide the best opportunity yet to optimize inputs.  However changes in plant population also affect nutrient need.  Discussions will focus on how the use of sub-field management changes, such as variable population, affect nitrogen needs and dynamics.  Pros and cons of various N management strategies in response to other sub-field management decisions will also be covered.
