We advocate the soil microbial diversity and its vitality value as a positive environmental assessment in the environmental accounting to show the result of the approach to the environmental friendly agriculture. It is considered to be important information to specifying the effort of the soilmaking. The diversity of soil microbial community and its vitality value is an index that shows biological richness of the soil. This index doesn’t pay attention to the species and the number of microorganisms but is measured only by the speed and the diversity of the degradative reaction to 95 different organic compounds and the rapidity in response. In general, the index of the soils enriched by the soil-making with the compost and the organic fertilizer indicates remarkably high compared with soil that amended with the chemical fertilizers. Moreover, it is known to decrease a value remarkably in the soil that causes soil-borne diseases by continuous cropping.
