...instead make it yourself like the Permaculturalist inside of you is pining for you to do. (OK, its early, so what if I screwed up my title and its joke.) [h=2]Make your own EM (Effective Microorganisms)[/h] EM is a blend of beneficial microorganisms developed by Teruo Higa, a professor at the University of the Ryukyu in Japan. These microorganisms improve the health of the soil, the plants, water and humans by breaking down organic matter in the soil, fixing nitrogen from the air, and feeding and protecting plants and animals. The organisms included are primarily yeast and pro-biotic photosynthetic bacteria and lactic acid bacteria. Buying EM is quite expensive, and you actually can make yourself at very minimal cost. In Asia, they even further process the EM into 4 types of EM (EM1, EM2, EM3 and EM4) and become much more effective and best depending what you will use the EM for. Here is simple way to make your own EM. EM1 is the original trademark product and contains a group of bacteria primarily lactic acid bacteria (lactic acid produced in metabolism), yeast, and photosynthetic bacteria. EM1 contains only three types of microorganisms in ideal proportions. EM2 is a mixture of more microorganisms, which is about 10 types and 80 species. Microorganisms, like many in EM1, also exist together as a consortium. The main microbes that exist in the EM2 is a photosynthetic bacteria, fungi, yeasts or molds, and so on. Made in liquid culture medium with pH 7 and stored at pH 8.5. The population of microorganisms in the solution is about 10 (9) or 1 billion cells per gram of fluid. EM3 consists of approximately 90% of bacteria photosynthesis and the rest are of other microorganisms. EM3 was cultured and stored at pH 8.5. Microorganism population in the fluid is also about 10 (9) or 1 billion cells per gram of fluid. EM4 consisted of 90% Lactobacillus spp. and microorganisms that produce lactic acid more. EM is made by culture in liquid medium was acidic pH of 4.5. The number of microorganisms retained the same as above, ie 1 billion per gram of fluid. That’s the main difference between EM1, EM2, EM3, and EM4. So in principle, the differences caused by the content of microorganisms of each type of EM is. The one that mostly used in Asia to boost farming and fisheries is the EM4. Materials: - Vegetables waste, especially beans - Fruit skin peels (papaya, banana, rambutan, mango, etc..) - Cheap Bran - Brown sugar - Rice water (the water you use to wash rice before you cook it) Method: - Mixed vegetable waste, fruit peels and bran. Place the instance in a bucket or container. Close and stir occasionally, leave for one week to rot and then it become EM (EM1). EM stands for Effective microorganisms that will accelerate the composting process. - EM1 liquid waste is mixed with vegetable and fruit peels. Then keep again for a week. It will develop a new liquid called EM2. - EM2 fluid mixed with bran, brown sugar and rice water and keep for about a week, it will become EM3. - Lets stand for about another week without adding anything. It will be EM4.
