​This presentation will help consultants, county agents, growers, and other practitioners in potato-producing states to understand how petiole analysis can be used as a diagnostic tool to help improve nutrition of the potato crop. Specifically, in this presentation, practitioners will learn the principles behind using tissue nutrient analysis for crop production, the proper procedures for taking a petiole sample, how to interpret the results following analysis, and use of petiole nitrate analysis as a guide for in-season nitrogen fertilizer application. By the end of this presentation, the practitioner should know more about appropriate use of petiole analysis for potato production.
