个人简介
Bartlett is best known for research and publications on manganese (Mn), chromium (Cr), and fundamental oxidation-reduction (redox) chemistry in soils. He was also responsible for the refined character of the Vermont Soil Test using measures of exchangeable aluminum (Al) to predict amounts of lime needed to raise soil pH to desired levels for crop production. This modification of the Vermont Soil Test exemplifies how Bartlett used fundamental soil chemical knowledge of Al and soil pH in a practical application to agriculture.
One of his aphorisms was “We all should fall upon our knees and sing out praise for manganese.” His passion for Mn developed from research with his graduate students that showed its redox reactions were cycles. and that a Mn cycle could oxidize, non-toxic, relatively insoluble Cr(III) to the toxic, soluble Cr(VI). Coupled to the Cr(III) oxidation reaction by Mn(III,IV) (hydr)oxides is the reduction of Cr(VI) to Cr(III) by electron-rich forms of organic matter, iron [Fe(II)], and sulfur (e.g., sulfide, H2S). Bartlett's new thinking and research results on the soil chemistry of Mn significantly refined our understanding of the thermodynamics and reactions of this metal, and his ideas were cited and widely influential in diverse fields of environmental geochemistry, clay mineralogy, soil and water chemistry, and environmental science.
