| − | |Introduction=Every year, the waste production of French people is about 320 kg per person (about 90 bags) with 120kg of organic waste that could be recovered. For instance, they can be used as fertilisers for crops | + | |Introduction= |
| − | | |
| − | It is quite simple to compost our organic waste in the countryside. In the urban areas, where ¾ of the French population lives, it is more complicated. Thus, the potential of waste composting is very important.
| |
| − | | |
| − | The compost production from organic waste encourages the cultivation of vegetables and fruits at home.
| |
| − | In urban areas, the objectives are diverse:
| |
| − | | |
| − | *Regain methods for cultivating plant
| |
| − | *Aim at/seek food security
| |
| − | *Cleanse the air/fight air pollution
| |
| − | *Eat quality and local products
| |
| − | | |
| − | '''Bokashi''' (“fermented organic material” in Japanese) is a very efficient composting method that can be adapted to the urban context. (It uses what we call the Efficient Micro-organisms (EM).) It implements the Efficient Micro-organisms (EM).
| |
| − | | |
| − | '''What are the Efficient Micro-organisms ?'''
| |
| − | | |
| − | In the wildlife, the degradation into humus of the (organic material) organic matter is done through the fauna and the flora consisted of fungus and bacteria. These “efficient” micro-organisms represent about 10% of the existing micro-organisms.
| |
| − | The EMs are a mix of 80 selected strains from these specific micro-organisms. Their presence in composting is used to imitate the performance of a healthy humus and to optimise the degradation of the organic matter.
| |
| − | | |
| − | The type of compost using these micro-organisms is called “Bokashi”.
| |
| − | | |
| − | It is worth noticing that the EMs can be used on crops (out in the field) in the ground to bring back life in poor soil. However, it is not to be used on a healthy soil as the EMs may be detrimental to the soil balance through their actions.
| |
| − | | |
| − | It is possible to [http://permaforet.blogspot.fr/2013/09/bokashi-dautomne-me.html locally source the strains] to make your own Efficient Micro-organisms. This still requires to master the process. Here is a link to try out/experiment this process (link).
| |
| − | The easiest way is to order the strains online. In France, you can order them through [http://www.synbiovie.fr/ Bertrand Grevet], an expert on the EMs.
| |
| − | There are two types of Ems:
| |
| − | | |
| − | *EM 1: these are concentrated strains that require one step before use : activating them with treacle / molasses ;
| |
| − | *EM A (for Activated Efficient Micro-organisms): the activation through the mix with treacle has already been done, however their shelf life is short (about 1 month). It is still better to source EMs A rather than EMs 1.
| |
| − | | |
| − | '''How does the Bokashi work ?'''
| |
| − | | |
| − | The bokashi is produced through the organic waste fermentation, inseminated with EMs A.
| |
| − | It operates in an anaerobic process (without any oxygen supply). It has to be hermetically sealed after each use for the good development of the bacteria, between 20°C to 25°C.
| |
| − | The composting outputs are:
| |
| − | | |
| − | * A very nutritious juice for the plants (which has to be diluted a hundred times with water)
| |
| − | * A solid compost full of minerals and micro-organisms
| |
| − | | |
| − | The process is pretty quick, which enables the use of a small container. Added to the fact that it is hermetically sealed, the bokashi fits well with an urban environment, and off the ground: it is closed, does not smell, and its juice is ready for use in off-ground cultivation.
| |
| − | This tutorial is edited with the help of Léon-Hugo Bonte, landscaper and decorator, proponent of the indoor off-ground cultivation, regular user of the bokashi and the EMs for several years.

| − | | |
| − | * To stimulate the degradation of the most recently added organic matter, return the composter during 15 days: the juice rich in micro-organisms will impregnate this waste and activate composting.
| |
| − | | |
| − | After 15 days: plant your vegetables by superimposing in a pot: a thin layer of fertile ground, a layer of your compost (1 cm) and fill the rest of fertile ground.
| |
| − | | |
| − | '''Note''': Your compost is now very rich in minerals but also in micro-organisms. The mineral mixture is an excellent food for plants. The bacterial flora will colonize the soil developing a rich living environment for the roots.
| |
| − | | |
| − | However, the bokashi is acidic: It is therefore important to place it at the bottom of the pot to prevent the roots from being in contact with it when repotting.
