This somewhat elaborate bokashi formulation included ingredients that supplement certain key nutrients, such as bone meal for phosphorus as well as fish meal and groundnut cake for nitrogen. This particular fermented bokashi fertilizer was comprised of a mix of dried chicken manure (100 kg/220 lb.), forest soil (80 kg/176 lb.), bone meal (45 kg/99 lb.), rice bran (30 kg/66 lb.), groundnut cake (30 kg/66 lb.), fish meal (30 kg/66 lb.), firewood ash (15 kg/33 lb.), charred rice husk (15 kg/33 lb.), raw sugar (1 kg/2.2 lb.), and wood vinegar (4 liters/1.1 U.S. However, in 2011, a development organization in Myanmar had their fermented bokashi fertilizer product analyzed at Mae Jo University in Chiang Mai. Such bokashi should be applied either topically over the root zone of established plants or mixed into the soil where new plants are being established.ĮCHO Asia has found very limited information regarding the nutrient content of bokashi fertilizers, probably due to the diversity of “homegrown” bokashi fertilizer mixtures across the region. Fermented bokashi fertilizer can be dried and stored for a period of six months to one year.īecause the nutrients of the finished bokashi product are fairly concentrated, and because inputs such as rice bran might need to be purchased, ARI recommends that bokashi fertilizer be applied somewhat sparingly. When the temperature of the bokashi fertilizer stabilizes and becomes the same as the surrounding air, and you can no longer smell the manure, it is ready to use. Moisture should be checked and adjusted to 50 percent as needed. The mixture should be turned whenever it becomes hot (around 60✬/140✯) usually once a day. The freshly mixed bokashi fertilizer should be covered with rice straw (or similar dried materials that are available on the farm) to retain moisture and heat. If no liquid can be squeezed out and the material still holds shape after being released, but crumbles when tapped, an appropriate amount of moisture has been reached. This level of moisture can be monitored by taking handfuls of the moistened materials and squeezing. While mixing, add water (with or without IMO, EM and/or FPJ) to provide about 50 percent moisture to the mixture. It is also recommended that the mixing process and fermentation take place under the shade of a roof to avoid strong sunlight, rain and wind. Although these supplemental microbe solutions are recommended to help stimulate the fermentation process for bokashi production, lack of access to such supplements should not deter anyone from making fermented bokashi fertilizer as beneficial microorganisms are already likely to be present in the soil and manure.ĪRI recommends that the materials be blended by dumping dry ingredients into a pile and using a shovel to mix the ingredients thoroughly.
