Dr. Heike Knicker

Since 2008, I am working as a Research Professor at the Instituto de Recursos Naturales y Agrobiología de Sevilla which is part of the Consejo Superior de Investigaciones Cientificas, Spain. Most of my research is dedicated to issues related to soil biochemistry. The spectrum of projects ranges from the investigation of the interactions and stabilization of organic carbon and nitrogen in soils and sediments to the impact of changing soil managing practices on quantity and quality of soil organic matter. In addition, I am interested in the effect of vegetation fires on soil organic matter stability, which led me to the study of biochars. Finally, the latter became a major topic of my present scientific activity. As a biochemist, I am highly interested in advancing analytical tools - in particular solid-state NMR spectroscopy - for an improved understanding not only of the structure and function of soil organic matter, biochars and related samples but also the interactions between the first and the latter. In 2016, I was awarded the Philippe Duchaufour Medal of the European Geosciences Union for outstanding research in the field of soil organic matter, in particular on the impact of fire on humic materials, and for furthering the knowledge of the origin and properties of pyrogenic soil organic carbon and nitrogen.

Transparency Declaration: Presently, I only receive funding for my biochar research from public research foundation grants. I am involved in four ongoing projects focusing on biochar. One is focusing on the application of biochar and related materials in horticulture, two others are related to use biochar and related materials as slow release N-fertilizer and in soil bioremediation approaches. I am a salaried employee, and have not received any private remuneration for either research or consulting.

 

Dr. David Laird

David Laird received his Ph.D. in Agronomy from Iowa State University in 1987. He joined the USDA-ARS as a research scientist in 1988 spending three years with the Soil and Water Management Research Unit in St. Paul Minnesota before joining the staff of the USDA-ARS National Soil Tilth Laboratory in Ames Iowa in 1991 where he served as both a research scientist and a lead scientist.  Dr. Laird joined the Department of Agronomy at Iowa State University as a professor in 2010, where he teaches ‘Responses to Global Resource Systems Challenges’, the senior capstone class in the Global Resource Systems major.  The class explores critical global resource issues facing developed and developing countries and challenges students to conduct original research and analysis and to strengthen their writing and communications skills.  Dr. Laird also teaches ‘Environmental Soil Mineralogy’.  This graduate level class explores the structure, chemistry, and function of clay minerals, clay-organic interactions in soil environments, and advanced analytical techniques.  Dr. Laird has mentored or co-mentored 20 graduate students and 10 visiting scientists and postdoctoral scholars. He is the author or co-author of more than 120 refereed journal articles and book chapters. A list of Dr. Laird’s publications is available here.

Dr. Isabel M. Lima

I am a research chemist with the ARS, Agricultural Research Service of the U.S. Department of Agriculture since 2001. I am located in New Orleans at the Southern Regional Research Center (SRRC).  I was hired then to find value-added solutions and technologies to the increasing manure disposal problem.  I then started to create and develop various biochars as well as upgrading them to activated biochars for environmental remediation, using various animal manures particularly those from CAFO’s, confined animal feeding operations.  It was determined that biochars produced from poultry manure are excellent at removing positively charged heavy metals from water. Two patents from this technology were filled. The biochar work has continued and expanded to also cover the development and manufacture of biochars from various plant and animal biomass materials to be used to remediate air, and soil. Most recently biochar has been produced from byproducts of sugar crops such as bagasse and applied onto fields for soil amending and crop enhancement.
