Abstract

Providing food for a rapidly growing world population relies on (i) increasing amount of food produced on cultivated land, (ii) increasing the genetic yield potentials, (iii) improving food transportation, and (iv) reducing food losses. This chapter addresses techniques that can be used to increase productivity on currently cultivated land and it provides a review of stable isotope applications in ecological research, examples on how to convert isotopic values from one unit to another, demonstrates how to use isotopic analysis to solve complex problems, and provides examples on how to determine a N fertilizer efficiency by using 15N-enriched and depleted fertilizers.
