A recent study from the USDA Economic Research Service (September 2011) reported that about one-third of U.S. cropland was found to meet the requirements for nutrient best management practices for rate, timing and method. This 2011 study reported that the cost to remove nitrate from drinking water was over 4.8 billion U.S. dollars per year and estimated that the cost of removing nitrate contributed by agricultural land management was about 1.7 billion U.S. dollars. The study reported that emission markets (e.g., water quality trading markets) could provide incentives to farmers to improve nitrogen use efficiencies and reduce nitrogen losses. This paper presents an improved version of the Nitrogen Trading Tool (NTT) with GIS capabilities, which was developed and released in 2010. This new, more advanced NTT has been enhanced with various features of the Agricultural EcoSystem Graphical User Interface (AgESGUI) modeling framework for enhancing and supporting GIS-based simulation and display of N losses to the environment (e.g., integrated NASA World Wind^TM technology and fully integrated tools for spatial statistical analysis). The potential to use the new, flexible AgESGUI technology with the new NTT concept/methodology to calculate N savings from improved agricultural management practices will be presented, including results from this GIS-based analysis for several U.S. regions and cropping systems, ranging from corn-soybean rotations in the North Atlantic region, to manure applications in the Midwest, to corn and vegetable production in the irrigated western United States.
