Jim Galloway (Univ. of Virginia) and colleagues have developed this tool to help communicate to the public the role that their actions have on the nitrogen cycle and the environment. Through this tool, we aim to educate people about nitrogen, how their lifestyles impact the nitrogen cycle, and how they can reduce their nitrogen footprint. The tool will be upgraded as our underlying scientific knowledge improves. You can view the N-Calculator at the following website: www.N-Print.org.
