GIS in Nutrient Management: A 21st Century Paradigm Shift
Track: Agriculture
Author(s): Harold Reetz, Quentin Rund, Scott Murrell

Initial ideas on using spatial information to manage crop nutrients focused on using yield maps and soil test maps to determine where fertilizer applications could be increased or decreased to correct deficiencies, save input costs, and make fields more uniform. Experience shows that this view is too simplistic, and in fact does not work. Many other factors are involved. Proper nutrient management means managing the different areas differently to optimize yield and profits. This revelation means GIS is even more important as a nutrient management tool for modern farmers. New technologies are being implemented to manage the variability in fields rather than remove it. Sensors, controllers, and a variety of GIS databases are becoming key components of nutrient management. This presentation reviews the tools and data bases and how they are being integrated into 21st century crop and soil nutrient management planning systems. ArcGIS and ArcPad make it work.
