One approach that can be used to distinguish between fruit and vegetables grown in organic and synthetic fertilizer is elemental analysis interfaced with isotope ratio mass spectrometry (EA-IRMS). EA-IRMS can be used to study a crop’s individual nitrogen isotope fingerprint – the subtle differences in the plant’s nitrogen components that can be used to identify the fertilizer used to grow it.
