Your Guide to Easy Fruit Tree Care

Episode 48: What are Biofertilizers? How can they help my fruit trees?

There is such a thing as "dead soil." And if your fruit tree is planted in soil like that, your fruit trees may never be able to reach their full potential. So what are biofertilizers and how can they help? 

In this episode, I speak to certified crop advisor Simon Neufeld 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.
