Bokashi composting is a method of composting first devised in the early 1990s. The composting is carried out in a sealed bucket. Some models available can be rotated to keep the ingredients well mixed. A Bran is used, to which a variety of micro organisms are attached. Known as Effective Micro Organisms (EMS). These have been chosen for their usefulness in activating decomposition of compost.
Unlike a normal compost heap, it is alright to put in such scraps as meat and left over dinner etc. The micro organisms work on it and prevent unpleasant smells from developing. To do this on a normal compost heap would represent a health hazard and attract vermin. With Bokashi composting, the bin is kept in the house.
Originally these EMS were used to improve micro organism activity in soil, and thereby improve soil structure. The usefulness in composting was discovered and developed later. the EMS are a combination of Yeasts and Fungi. The Bran is a carrier and spreader for these micro organisms. They work by speeding up composting, and at the same time prevent nasty smells.
Each time a fresh layer of kitchen waste is added, it is given a sprinkle of the Bran. A purpose made bin is used which has a tap at the bottom to drain off liquid, as well as a tight fitting lid.
When added to the soil, the Bokashi compost breaks down further and releases pro biotic organisms into the soil, which increases the soils natural fertility.
So far untried and tested by 'GardenAdvice', we are positive about this composting technique and will be carrying out our own trials and reporting the results on the website.
Keep watching for regular updates.
