This workshop aims to learn how to build a compost bioreactor, according to the Johnson & Su method. The compost is built according to the plans and explanations of Johnson & Su. 

​

Have living soil, i.e. rich in micro-organisms, fungi and soil fauna (earthworms, arthropods, etc.), is the key to setting up aregenerative cultivation system. Such a system has the ability to be self-sustaining by recycling organic elements, makes it possible to retain water more effectively and is moreresilientin the face of diseases, pest attacks, deficiencies, etc.

 

A good example of living soil is theforest litter. Naturally, time and the presence of plants in the soil make it possible to obtain suchecosystem. But we can also mimic these cycles of decomposition and obtain arich and living substratethanks tocompost.

 

It existsdifferent composting methodseach with its advantages and disadvantages. The method implemented in this training has several advantages : the " réacteur " is economical and easy to build, can be reused about ten times, makes it possible to obtain a compost rich in bacteria and fungi in 2 months, does not require turning actions, etc.

​

 

On the program of this training :

​

• Explanations ofhow living soil worksand its benefits for plant production ;

​​

• Presentation oftraditional composting methods(cold compost, vermicompost, Berkeley compost, etc.) ;

​​

• Explanation ofJohnson & Su method and construction of the bioreactor ;

​​

• If needed :preparation of organic matterto compost (grinding then soaking) ;

​​

• Reactor filling ;

​​

• Optionnel : 2 days later, the PVC tubes must be removed and interested people can attend.
