Areas of Interest
I am interested in the applications of basic principles of chemistry to problems in soil science. One important area of interest is the interactions of various elements with soil organic matter. Recently I have used x-ray spectroscopy to elucidate the chemistry of phosphorus, sulfur and mercury in soil organic matter. I also have worked with wild rice growers on problems related to plant nutrition and I continue a long-standing interest in the problem of iron deficiency chlorosis in soybeans.
