Biographies:
J. D. Etchevers is a Ph. D. who graduated from North Dakota State University with more than 50 years of experience in soil chemical analyses. He has worked in several Latin-American countries and in the USA. He has accomplished sabbatical years and short-term stages in various European countries. He is a member of the Mexican Academy of Science, Professor Emeritus of the Colegio de Postgraduados, and National Researcher Emeritus of the Mexican National System of Researchers. Dr. Etchevers has received numerous recognitions from the State of Mexico and professional and scientific societies of the continent. The soil analytical laboratory under his direction performs traditional soil chemical routines for evaluating soil fertility and, in addition, conducts research employing X rays, chromatographic (liquid and gas), potentiometric, TEM, and SEM microscopy techniques, among others.
Claudia Hidalgo is Dr. of Science who graduated from the Université de Nancy, France, with more than 30 years of experience in soil science, particularly in analytical chemistry and clay minerals. She has spent a sabbatical year in Spain and short-term stances in Europe and Latin American countries. She is a Full Professor of Soil Science at the Colegio de Postgraduados, Mexico, and a Mexican Soil Science Society member. Dr. Hidalgo is also a member of the Mexican National System of Researchers. Her main interest is in soil chemistry, particularly soil carbon and organic matter analysis, and the interaction of both with the inorganic clay minerals. She was responsible of the soil analytical facility at her institution for several years and has been an essential part of the Mexican soil analytical quality control program. In addition to her knowledge of soil analytical determinations, she operates the X-ray section, IR spectroscopy (MIR, NIR) and the automatized carbon and nitrogen facilities at the Colegio de Postgraduados soil fertility laboratory.
Abstract:
This webinar presents how to measure soil phosphorous by Olsen method, following the Standard Operating Procedure (SOP) harmonized by GLOSOLAN in 2021. The lecturers will provide an insight of the procedure, describing each step of the measurement, from sample preparation to quality assurance and control, focusing also on the health and safety measures. Participants will have the chance to raise questions and directly interact with the speakers in a Q&A session at the end of the presentation.
