Bokashi Compost

Compost and earthBokashi compost can also be made by layering organic materials about 15-20 centimetres thick on a water resistant material such as a tarpaulin and then as each layer is added watering the layers with a solution of one part EM-1®, one part molasses to one thousand parts of water (1:1:1000) as they are added to the pile. This is equivalent to about three teaspoons of EM-1® and three teaspoons of molasses to fifteen litres of water. The amount of water you use to dilute the EM depends on the moistness of the material used.

It may take up to fifteen litres of the diluted solution per cubic metre of materials in the pile, depending on the material available. Any organic material such as grass, weeds etc, can be used. Ensure the materials are sufficiently covered with the solution to be wet but not too wet. There should be no more than thirty percent moisture content in the heap. You can check this by pressing the materials with your hands into a lump – the lump should remain whole and no moisture should leak from it. If it is too moist mix in some dry materials

Then cover the pile to keep out rain with the remainder of the tarpaulin, a plastic cover or even a piece of old carpet etc. The pile should heat up and may need to be turned. Leave to ferment for at least six weeks and the compost should be ready and is an excellent plant fertiliser and soil conditioner.

The compost produced is not brown and crumbly like traditional composts and looks very similar to what it looked like when it was placed in the pile. However the EM has converted the materials to a highly nutritious plant material. The compost can now be used as you would any other compost, use as a mulch around plants or incorporate the compost into the soil.

EM prefers warm weather and goes dormant when the temperature drops below 6°C, however once the temperature rises above this the EM becomes active again.
