Detecting Substitution of Organic Tomatoes with Conventionally Grown Products Using δ15N ‰ Analysis

Authentic samples of commercially produced organic and conventionally grown tomatoes were collected and analysed for their δ15N composition in order to assemble datasets to establish if there were any systematic differences in nitrogen isotope composition due to the method of production. The tomato dataset show that the different types of fertiliser commonly used in organic and conventional systems result in differences in the nitrogen isotope composition of this crop. A mean δ15N value of +8.1‰...
