In regards to BIM, I'd say there are other things that would be better to invest yourself into. BIM is a simplified inferior offshoot to KNFs I.M.O. (Indigenous Micro Organisms) and the I.M.O. will produce better results. There are other easy and effective methods that offer alternatives to BIM. I.M.O. is an aerobic collection and composting process, and BIM doesn't follow the same final aerobic processesess. JADAM is an anaerobic system, created by Hankyu Cho's very own son, Youngsan Cho, and the JADAM Microbial Solution (JMS) is a compost tea of leaf mold, potato (for food), and sea salt (micronutrients). BIM appears to be a fusion of a JMS and I.M.O., and doesn't achieve the effectiveness as either, neither does it appear to be based on any apparent scientific reasoning. Overall, I feel the owner of the unconventionalfarmer.com tried to pass off Korean Natural Farming as his own by renaming things and changing the instrutions of the ingredients and pass off BIM as his original system. It works, but not as effective as KNF, and I would say invest yourself into KNFs I.M.O. or JADAM over BIM. Gil, the owner of the website, is a natural farmer from the Phillipines and many farms in the Phillipines, as well as Southeast Asia and Asia, farm similar to these methods. But on a side not, many farms in the Phillipines are adopting JADAM into there farm.
