  1. APAN2007 on August 29, 2007 A novel system for measuring and sharing vitality of soil microbial community in worldwide farmer/researcher network. Kazunari YOKOYAMA(NARO) Akira MINEMURA(GIFU pref.) Chiharu MORIKAWA(ISHIKAWA pref.) Seishi YOSHIDA(NAGANO pref.) Masayuki MAEDA(NIIGATA pref.) Yoshihiro HASHIMOTO(SAKATA seed co.)

  2. 1.4 billion peoples beyond exportable supplies China depends on irrigated land to produce 70 percent of the grain for its huge population of 1.2 billion people, but it is drawing more and more of that water to supply the needs of its fast-growing cities and industries. As rivers run dry and aquifers are depleted, the emerging water shortages could sharply raise the country's demand for grain imports, pushing the world's total import needs beyond exportable supplies.

  3. Serious concerns for sustainability and environmental safe Impact of human activities onto soil biotic environment Difficulty in scientific research of impact on soil biotic Environment. Difficulty in evaluation of soil microbial community. Difficulty in rational decision making on the environmental risks. Outbreak of “Techno-phobia”…. Escapism from prior investments for potential risks in the future.

  4. What the soil microbes are: １０１０～１１units/g More than 1000 spp/g Mostly unknown Vast of labor Invisible Only 1/1000 to 1/100 are culturable Very diverse and gigantic but impossible to know what and how many Impossible to apply conventional concept Need to develop a new concept of diversity

  5. distanceA-B StrainA StrainB distanceAB-C StrainC distanceABC-D StrainD Taxon-independent Diversity Index = (sum of distances)2/number of strains

  6. Diseased soil Suppressive soil Measuring balance of information structure of the components orientated by the MDS (Multi Dimensional Analysis) The natural suppressive soil had highly balanced structure

  7. Relationship between fertilizer and diversity of Soil microbial Community Relationship between yield and diversity of Soil microbial Community

  8. What we found : We have discovered that the diversity of soil microbial communities in the agricultural fields has been shrinking world-widely in the case without human positive care.

  9. OmniLog PM System

  10. Soil vitality as a GIS information

  11. 熱水消毒 Ping point management of soil vitality

  12. The ShangHai Institute is now under construction We open around Dec. in 2007!

  13. Next Steps • Business Models • Soil Vitality Analysis and Consulting • 200 soils/month/person • World Soil Vitality map • Collaboration with the GIS • Environmental Friendly Rural Development • Environmental Reforming
