| Plants are photoautotrophic organisms being able to synthesize all metabolites and macro-molecules on the basis of light, CO2, H2O and 14 inorganic elements taken up from the soil. As plants are confined to the environment in which they germinate, this means that the plant ionome, metabolome and proteome are heavily influenced by soil mineralogy, climate and not least agricultural management. Organic plant products within the European Union are produced according to a specific set of regulations, which e.g. implicate that organic plants are cultivated without pesticides and synthetically produced nitrogen (N) fertilizers. In addition, N fertilizers are often used in lower amounts relative to conventional agriculture. Over more than a decade it has been... |

| Plant tissue analysis is a valuable tool for evaluating the nutritional status and quality of crops and is widely used for scienti fi c and commercial purposes. The majority of plant analyzes are now performed by techniques based on ICP spectrometry such as inductively coupled plasma—optical emission spectroscopy (ICP-OES) or ICP—mass spectrometry (ICP-MS). These techniques enable fast and accurate measurements of multielement pro fi les when combined with appropriate methods for sample preparation and digestion. This chapter presents state-of-the-art methods for digestion of plant tissues and subsequent analysis of their multielement composition by ICP spectrometry. Details on upcoming techniques, expected to gain importance within the fi eld of... |

| The commercial market for high-value plant products is steadily increasing. Consumers are willingly paying premium prices for plants that originate from specific geographical regions or are produced according to certain agricultural management practices. This has significantly enhanced the market shares of organically grown plant products but has simultaneously increased the risk of food adulteration and fraudulent activities. Consequently, sophisticated analytical principles are currently being developed to enable discrimination of organic and conventional plants and ensure compliance with the regulations of organic agriculture. Some of the most promising principles for organic authentication are based on atomic spectroscopy which encompasses several... |
