Regenerative Agriculture Podcast

In this episode of the Regenerative Agriculture Podcast, John interviews French agronomist, Olivier Husson, whose pioneering work on soil pH and redox potential provides a groundbreaking look at what goes on within the soil.  Olivier has focused a large part of his research on the study of reduction-oxidation (redox) in rice production, where the crop is grown in paddies in anaerobic conditions. These conditions are ideal for the study of Eh. Eh, the short notation for redox potential, is a measurement of the availability of electrons, whereas pH is a measurement of the availability of protons. In order to gain a full picture of the soil’s nutrient profile, we need to assess both the pH and the redox potential at the same time.  In this interview, Olivier details:  the difference between Eh and pH  how the Eh profile changes based on photosynthetic activity  how electrons in the soil are key to reversing oxidation and absorbing nutrition from soil mineral reserves how Eh determines water absorption capacity
