M. Susan Erich
Professor of Soil Chemistry
Degree: Ph. D. 1984, Cornell University
Location: 102 Deering Hall
Professional Interests: Plant-soil interactions, soil organic matter, nutrient availability from alternative fertilizer materials
Teaching: PSE 121 Human Societies, Soil, and Water: The Unbreakable Link, PSE 440 Environmental Soil Chemistry and Plant Nutrition
Research: My applied research relates to the effects of soil amendments on soil chemical and physical properties. More basic research investigates the chemistry and formation of soil organic matter, particularly soluble and extractable fractions. I have investigated the effects of naturally derived organic ligands on the solubility of phosphorus in soils, as well as environmentally and agronomically appropriate soil testing for phosphorus. I also serve as Director of the Maine Agricultural and Forest Experiment Station Analytical Laboratory and Soil Testing Service.
