A novel system for measuring and sharing vitality of soil microbial community in worldwide farme
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.
1.4 billion peoples
beyond exportable supplies
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.
1010~11 units/gMore than 1000 spp/gMostly unknownVast 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
What the soil microbes are:
StrainA
StrainB
StrainC
StrainD
distanceA-B
distanceAB-C
distanceABC-D
Taxon-independent Diversity Index= (sum of distances)2/number of strains
Suppressive soil
The natural suppressive soil had highly balanced structure
Diseased soil
Measuring balance of information structure of the components orientated by the MDS (Multi Dimensional Analysis)

Yield(kg/a)Relationship between yield and diversity of Soil microbial Community
Relationship between fertilizer and diversity of Soil microbial Community
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.
OmniLog PM System
Soil vitality as a GIS information
熱水消毒
Ping point management of soil vitality
The ShangHai Institute is now under construction
We open around Dec. in 2007!We open around Dec. in 2007!
Next Steps
• Business Models– Soil Vitality Analysis and Consulting
• 200 soils/month/person
– World Soil Vitality map– Collaboration with the GIS
