Live Panel with Dr. David Johnson, Dr. Carla Portugal & Dr. Elaine Ingham (Hosted by Brian Vagg)
Join the live panel with Dr. David Johnson, Dr. Carla Portugal and Dr. Elaine Ingham. Brian Vagg hosts this live panel.
Our Live Panels are an opportunity for our experts to get to know each other, share ideas, and ask each other questions. The audience also has the opportunity to submit questions for the panel. Live Panels are held in Zoom Webinar.
The Live Panels will be followed by separate Meet & Greet sessions where each speaker will move into a separate Zoom Meeting for a moderated Q&A with audience members.

Dr. Carla PortugalInstructor, Mentor, Researcher, and Translator for the Soil Food Web SchoolDr. Carla Ribeiro Machado e Portugal speaks Portuguese, English, and Spanish while working as a simultaneous translator/interpreter for Portuguese-English, and English-Portuguese. She began her academic career at the Federal University of Uberlândia, graduating in 2004. She then completed a Master’s in Environmental Engineering, relocated to the United States, and completed her Ph.D. in Environmental Sciences after researching the biostabilization of unpaved roads to minimize the impact of hydric erosion. Her research has resulted in 27 empirical listings. Since 2008, Dr. Portugal has served as a co-founder of a consultancy company in Brazil for Environment and Agriculture projects. She consulted with the Brazilian federal government in developing and approving one of the few Category II centers within UNESCO focused on Education for Water management for Portuguese-speaking countries. She also worked for the government of Minas Gerais developing strategies to enhance the abilities of small farmers and settlements to achieve better agricultural practices towards organic and sustainable practices. She served as Environmental Education Supervisor and Environmental Legislation Supervisor at Instituto Inhotim, a significant Botanical Garden in Brazil. Since 2019, Dr. Portugal has served as an Instructor, Mentor, Researcher, and Translator for the Soil Food Web School. Her robust skills consistently guide her international students toward success.

Dr. David JohnsonResearch Scientist, Sr. Molecular Biologist NMSUDr. David C. Johnson is a molecular biologist currently working with: California State University Chico, Arizona State University, Texas A&M, USDA’s Natural Resources Conservation Service, and growers exploring paths to improve food security, reduce atmospheric carbon dioxide concentrations, and increase productivity and profitability through the development of beneficial soil microbial communities in farm and rangeland soils. He is an Adjunct Professor at the Regenerative Agricultural Initiative (RAI) at California State University, Chico and the Director of the Institute for Sustainable Agricultural Research at New Mexico State University in Las Cruces.
David’s current research, in soil microbial community structure and function, has opened a window for viewing the interdependence between plants and soil microbes towards improving plant growth and soil fertility. Optimization of these plant-microbe associations promotes: improved soil fertility, faster growth of crops, improved plant water use efficiencies, and greater soil carbon storage capabilities. These benefits provide a path to significantly increase crop productivity and reduce greenhouse gases within a regenerative agricultural system.

Great reinforcement of key concepts in regenerative argiculture.
It is always great to hear the call to arms (from the panel) – that testing is critical in order to know and understand the mechanism of what is really happening in the soil food web system. We can all contribute to this. If we can all share and collaborate – we are in effect as a healthy biom; ‘quorum sensing’. Mimic nature!
I am new to the SFWS, however, i am excited to continue my journey of testing, and trial and error for the benefits it brings to local knowledge and importantly; building soil sponge 😉
This is the great journey to tread; the reimagining (and knowing) of planetary existence and evolution. It is indeed exciting times to be an early adopter!
Elaine looks so energized and full of wonder when discussing the new possibilities from Dr James Whites’ earlier presentation on how bacteria is ‘farmed and consumed by plants’. A whole new world to share together – the very fronteir of our field. I too was completely blown away from James ground-breaking discoveries.
Thank you for this great discussion.
