470: David Stark on Soil Microbes.

Getting serious about the microscopic life in soil.


In This Podcast:

Retired after years of leadership in Monsanto, David Stark was asked to mentor a young company making what was essentially compost tea. Reluctantly and with some concerns over the science, he agreed and now is excited to share what he has learned about soil science and plant health. Grateful for not turning down the request, he now can help teach about soil and plant health and explain about the various microbes in the soil and the essential roles they play.

  1. Thank you, Farmer Greg for another insightful interesting and relevant podcast! I especially like the fact that you did not edit it Dr Stark’s favorite book! I appreciated hearing from a well educated person that faith in a Creator is possible, reasonable and sound. I LOVE your podcasts!
