Outline of Final Research Achievements |
The soils from fruit orchards from all over japan had their microbial community (bacterial and fungal) determined by amplicon gene analysis (Illumina MiSeq 250bp). The soil microbial biomass (C, N, P and K) and activity, represented by enzymes (Phosphatase, Dehydrogenase, Arylsulphatase, b-gluosidase, protease and Urease) were also determined. Furthermore, soil chemical properties: pH, Total N, Total P, Available P, Amourphous fraction, and EC were analysed. The abundance, diversity, and composition of the microbial communities were specific according to fruit type and region (Location). The estimated microbial richness was generally higher in northern regions than in those from southern. Similar pattern was found for microbial biomass N and C, and enzyme activity. Considering the relationship between these data, the enzyme activities were positively correlated to bacterial richness, but not with fungal ones. Also, the soil microbial biomass P had correlation with amourphous fraction.

Academic Significance and Societal Importance of the Research Achievements |
This research could demonstrate that the soil characteristics (microbial community, biomass, activity and chemical properties) can range according to land using in fruit orchards. Especially the high values of diversity and enzyme activity could confirm the influence of organic matter.
