Olivier Husson: Redox Potential and Reduction-Oxidation Reactions | 2019 Soil & Nutrition Conference

The Role of Redox Potential and Reduction-Oxidation Reactions Olivier Husson, PhD “What drives life is a little electric current, kept up by the sunshine” was the elegant summary of Albert Szent-Györgyi, a Nobel Laureate in Physiology. Together with proton exchanges (acid-base reactions), electron exchanges (reduction/oxidation reactions) regulate the functioning of soil, plant, and microorganism systems, and largely impact soil, plant and animal nutrition and health. pH( measuring the availability of protons) and Eh (redox potential, measuring the availability of electrons) can be used as indicators of both soil, plant and animal health. In this workshop, we will “follow the electrons“ in a “one health“ approach to show how the cropping practices impact soil Eh-pH, which in cascade impacts microbial activity and plant nutrition, which impacts plant health and fodder quality, and as a consequence, impacts animal nutrition and health.
