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.

Speaker Bio: 
Dr. Olga Walsh is a Cropping Systems Agronomist and Extension Specialist with the University of Idaho’s Parma Research and Extension Center. Olga was hired to direct the Cropping Systems program in September 2014. The program’s primary goals are two-fold: 1) develop applied research projects that address pressing needs of crop producers in Idaho and the Pacific Northwest region, and 2) conduct educational outreach to agricultural professionals. The program is currently focused on developing scientifically-based, field-tested, unbiased grower recommendations that would improve sustainability and profitability of farming operations. The current projects are in wheat, barley, dry beans, alfalfa and corn. Olga’s training and background is in Soil Fertility and Plant Nutrient Management. Originally from Russia, she obtained her BS degree in Soil Science at St. Petersburg State University, Russia. She received her MS and PhD degrees at the Oklahoma State University, Stillwater, OK. Prior to her UI appointment, she served as a Soil Nutrient Management Specialist with the Montana State University for 4 years. Olga is a published author on a variety of precision agriculture topics and has presented at numerous national and international precision agriculture events. Olga manages and writes for a Cropping Systems Blog (Idaho Crops & Soils), and writes and publishes a monthly newsletter – Idaho Crops & Soils News.
