Biochar

With Canberra City Farm

Workshop description

In this workshop we will convert the farm's orchard prunings and other organic material into biochar for use in the gardens.  This is a hands-on workshop where you will participate in:  

  • loading the wood into the retort  

  • firing up the retort  

  • learning how to hydrate and inoculate the biochar   

  • preparing soil under trees, and   

  • applying the biochar to the soil  

We will describe alternative ways of making biochar without using a retort.  We will also discuss the advantages of adding hydrated and inoculated biochar to your garden soil. 

Target audience(s)

Anyone interested in improving the fertility and water holding capacity of their garden soil.  Beginner gardeners as well as more experienced gardeners are welcome to attend. 

Workshop length

Approximately 4 hours. There will be a short lunch break. 

Workshop requirements

As this is an outdoor practical workshop, participants should bring gardening gloves and wear sturdy, closed shoes and appropriate gardening clothes for the weather conditions.
