Using nitrogen isotopes to measure nitrogen content in soils is a valuable way to distinguish organic and conventionally fertilized uplands. A recent paper published in J. Agric. Food Chem. Rogers, K.M. uses nitrogen isotopes for determining the type of farming method used by a farmer. Verenitch, S., and Mazumder, S. used nitrogen isotopes to validate the authenticity of organic produce in western North America.
