Outline of Final Research Achievements

Since 1987, the Nagoya University affiliated farm has maintained the field under long-term treatment of organic waste-recycled composts. In the field, there are six areas: fertilizer-free area, chemical fertilizer area, chemical fertilizer + cow manure area, chemical fertilizer + coffee compost area, chemical fertilizer + bark compost area and large amount cow manure area. In this study, we observed that soil of the large amount cow manure area has the suppressive effect on soil-borne diseases and the promotion effect on plant growth and clarified that soil microorganisms are involved in the disease suppressive effect by using sterilized soil. Furthermore, soil microbiome analysis of the field using the next-generation sequencer clarified that the population structures of bacteria and fungi in soil were greatly changed by not only the presence or absence of organic compost application but also the type and amount of organic composts.
