David's research, in soil microbial community structure and function, has opened a window for viewing the interdependence between plants and soil microbes. Optimization of these plant-microbe associations promotes: Restoration of soil fertility; Improved growth of crops; and Increased plant-water-use efficiency, soil’s water holding capacity, soil microbial-carbon use efficiencies and soil carbon storage capabilities. These benefits provide a path to significantly increase farm and ranch productivity and profitability due to better plant, soil, and ecosystem health. Rebuilding a soil’s microbial community population, structure, diversity and biological functionality will also provide a robust and practical mechanism to reduce atmospheric carbon dioxide within a regenerative agricultural system.
Dr. Johnson and his wife, Hui-Chun Su Johnson, are co-creators of Johnson/Su Compost Bioreactor. David is a molecular biologist conducting research as Research Scientist at New Mexico State University in Las Cruces, NM. He works with growers, and researchers from: Arizona State University, Texas A&M, University of North Texas, Colorado State University, USDA’s Natural Resources Conservation Service, the Globetrotter Foundation, the Thornburg Foundation, the Laird Norton Family Foundation, the Mighty-Arrow Family Foundation, and Cruces Creatives. Working with these entities, David and they explore paths to improve food security, reduce atmospheric CO2 concentrations, and increase farm and rangeland productivity and profitability through the development of beneficial soil microbial communities.
