Nitrogen Isotope Relationships between Crops and Fertilizer:  Implications for Using Nitrogen Isotope Analysis as an Indicator of Agricultural Regime

The effect of fertilizer type, amount of fertilizer applied, growing medium, and water type on the nitrogen-15 content of carrots, tomatoes, and lettuces has been investigated. Crops grown using synthetic nitrogen fertilizer were isotopically lighter than those grown using pelleted chicken manure. F...
