M. Susan Erich

Professor of Soil Chemistry

Degree: Ph. D. 1984, Cornell University2013-Sues-photo-166x250
Phone:
207.581.2997
Email: erich@maine.edu
Location: 418 Deering Hall

Professional Interests: Plant-soil interactions, soil organic matter, nutrient availability from alternative fertilizer materials

Teaching: PSE 440 Environmental Soil Chemistry & 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.
