Redox and Micronutrient Solubility.

During the late 1970s and 1980s, Willard Lindsay and his students aggressively pursued increasing our knowledge about redox relationships in soils. Beginning with iron, manganese, and nitrogen, Dr. Lindsay's team eventually expanded into lesser known micronutrients (e.g., selenium) and trace contaminants (chromium, arsenic, nickel).  Not all of the research was fruitful, but some of the results led to important discoveries. Although most of the laboratory research was conducted by graduate students and post-doctoral associates, Professor Lindsay performed some of the experiments himself. Underlying all of the work, of course,  was the foundational concept of equilibrium chemistry. Some of the more important results from published research will be discussed as well as the implications of the studies. Recent developments inspired by this research will be presented.
