Improving nitrogen (N) and water use efficiency for cropping systems is of significant agronomic, economic, and environmental value to stakeholders. Precision agriculture technologies and methodologies offer potential opportunities for improving N and water management. The most promising way to improve the efficiency of agricultural inputs – is to apply them based on site-specific crop requirements. Sound N and water recommendations should take into account spatial (field-to-field, within a field) and temporal (within a season, among seasons) variability in soil residual N and available water. Crop yield potential response to N and water varies greatly depending on a variety of environmental factors. Crop canopy sensors enable us to access crop nutrient and water status mid-season and have been successfully utilized to predict yield potential in many crops around the world. Incorporating environmental characteristics, such as an estimate of crop water status, should further improve N and water recommendations. Conducting precision agriculture research in on-farm conditions offers several key advantages. It encourages collaboration of crop producers with the research institutions, includes growers in the management decision process, and generates results the local growers can trust. Furthermore, on-farm projects enhance the educational outreach and encourage the acceptance and adoption of precision agriculture technologies and methodologies. The webinar will provide information on completed and current on-farm projects focusing on precision N and water management. In addition, an overview of key components required for successful planning and implementation of on-farm studies will be covered.
