In this episode, certified crop advisor Simon Neufeld talks about soil biology. Why is it important to have a lot of good organisms in your soil? What services do they provide? And if you do have "dead soil", is it possible to use so-called "biofertilizers" to bring it back to life? Simon is the Chief Agronomist at Earth Alive Clean Technologies, a company that develops environmentally sustainable microbial products which they say can replace many of the damaging chemicals that farmers use today.Read an article about the importance of soil bacteria when growing fruit trees and other plants here.
