1 Arbuscular Mycorrhyzal Fungi produce a Glomalin glue which aggregates small soil particles Fertile Soil is “aggregated” This increases water & air holding capacity, increasing soil tilth and biomass yields Biochar seeds aggregate formation to absorb dissolved organic matter through wet and dry cycles to build long-term carbon storage click to continue Terra Preta Research

2 Biochar added to A. manguim manguim seedlings at age 6 months, height & diameter significantly increased Siregar (2004), Forest & Nature Conservation Research & Development Center, Indonesia 0% 10% 15% 20% click to continue Terra Preta Research

3 Effect of Biochar on Soybean yield and root nodule formation Makato Ogawa Kansai Environmental Japan click to continue Terra Preta Research

4 plantation covered by 5cm rice husk biochar earthworm population increased soon after treatment due to neutralization of topsoil Effect of Biochar on A. mangium root growth & nodule formation Okimori & Yamato (2002), Indonesia click to continue Terra Preta Research

5 Research after: Oct. 1999 Ogawa 1999, Kansai Environmental before: Sept. 1998 click to continue Terra Preta Biochar Benefits Existing Forest click to continue click to continue results 13 months after treatment Dr. Ogawa reports in Japan biochar use to enhance plant growth isn’t experimental. Japanese government made it an official approved crop & soil management practice. Dr. Ogawa works for Kansai Environmental, a division of Kansai Electric, one of Japan’s largest power companies. Kansai currently has projects in Australia and Thailand using biochar in soil to create carbon credits. Plans include a one million hectare soil restoration project in Australia to grow cash crops and create carbon credits. Growth of pine root and mycorrhizae formation started at 5 to 6 months after treatment
