From the Preface: The treatise Advancement in Micronutrient Research is a summary of important new findings on trace elements nutrition and interactions and of basic and applied needs in microelement nutrition. It also provides a useful perspective of important progress and fruitful research opportunities.

For new workers in this field, a specialized book on micronutrient research consisting of manifold information and references has been realized to be extremely important to quickly learn above the total area of trace element nutrition including the hardly known trace elements and obtain help in a precise manner including genetic materials needed for research.
