Abstract
Different nitrogen fertilizers produced in Egypt were analyzed mass-spectrometrically for their15N content. The results indicate that nitrate fertilizers are relatively enriched in15N compared with ammonium fertilizers. The isotopic fractionation of nitrogen encountered in the production processes of fertilizers are discussed.
