Our solution utilizes a microorganism-immobilized biochar, Soratan, developed as a soil microbiome technology spin-off from Nagoya University, Japan. The technology employs a microbial consortia featuring over 1,000 species, including ammonifying and nitrifying microbes.
The biochar matrix acts as a protective medium that enhances microbial establishment and persistence both within the biochar and in the surrounding soil. This stabilization is achieved through a proprietary treatment. Our biologically engineered biochar improves the degradation of organic compounds by optimizing the nitrogen cycle, resulting in the fast availability of nitrogen compounds (e.g., nitrate nitrogen) for plants in the field. Our technology is currently being tested in Japan and several countries worldwide, including the USA. Adopted by 600+ farmers in Japan, our field trials confirm the efficient conversion of organic nitrogen, showing high nitrate (NO3-) availability after only 27 days. This efficiency accelerates soil regeneration from several years to approximately one month, providing measurable results such as an average yield increase of over 20% in commercial fields compared to conventional chemical fertilizers. Compared to standard biochar, Soratan demonstrates markedly higher potential for nitrogen cycling. It utilizes locally available, organic-certified ingredients, meeting all environmental safety requirements.
