How to make basic rice bran bokashi. You can make bokashi fertilizer full of lactic acid bacteria with rice bran and yogurt. Bokashi fertilizer is a homemade fertilizer that you often use if you are doing vegetable gardening, but if you mix oil cake or chicken manure to make bokashi fertilizer, it is difficult to use if you do not want to add nitrogen or phosphoric acid. So if you make bokashi fertilizer only with rice bran, which is the base of bokashi fertilizer, you can add ammonium sulfate to the bokashi if you want to add nitrogen, or add wood ash to the bokashi with only rice bran if you need potassium. There is no need to make several types of bokashi, such as bokashi with high nitrogen and bokashi with high potassium. This is a versatile bokashi fertilizer made only from rice bran, which can be added to the amount of fertilizer required depending on the vegetable. It is very easy to make bokashi fertilizer. All you need is rice bran, water, and a fermentation promoter. This time, I used yogurt with live lactic acid bacteria as a fermentation promoter. Yogurt drink is sterilized, so it has no effect as a fermentation promoter. You can also make it with natto. There are no set amounts. All you need to do is mix well and not add too much water. Too much water is often the cause of failure when making bokashi. Add water little by little. As you add water, squeeze it lightly and it should crumble. This is the optimum amount of water. Over the first few days, fermentation heat of around 50°C will be generated. After about 10 days, the temperature will reach the same level as the outside air and the heat will subside. This is the signal that fermentation is complete and the lactic acid bacteria rice bran bokashi fertilizer is ready. It can be used immediately, but any remaining amount can be stored by hanging it in the shade in a sandbag.
