Convert agricultural waste into microbial inoculants and enrich soil microbiota in Southeast Asia

“We want to expand the plantation that can produce sustainably in a well-conditioned soil environment by using CHITOSE’s original technology which converts waste to raw materials.”

Southeast Asian palm plantations holds 85% share of the world’s palm oil market. However, the actual situation is severe due to the high damage done to the soil in order to gain a higher yield in a short time, which is causing various blights or obstacles to continuous cropping by the pathogenic bacteria from losing microbial balance in the soil. Thus, we established a way to produce microbial materials that suppresses the target pathogenic bacteria by using our original composting technology that recycles agricultural organic wastes, which traditionally can only be disposed. Now, we are developing, producing, and marketing of the microbial materials in collaboration with palm plantation.
By aiming to create a new plantation system that cultivates crops while enriching the bacterial flora of the soil, we are expanding the creation of sustainable economic value.

Background issues

  • The soil layer where crops grow are being damaged at a rapid rate in the plantations of Southeast Asia because in spite of the soil metabolizing by breaking down the microbes, there is no supply of the organic matter.
  • Moreover, overused soil and palm trees are damaged by the pathogenic bacteria because of the over pursuit of short term yield improvement and production cost reduction which depend on chemical fertilizers.
  • As a result, we have to consider desertification of the farmland as a worst-case scenario.

Our technologies

  • Technology to produce CSF (Chitose Soil Flora) that enriches soil microbiota
  • Technology to visualize the richness of soil microbiota
  • Technology to create economic value in enriching soil microbiota

Current status

  • The product is being sold in some countries.
  • The project to incorporate our products and technologies into the process of a large-scale plantation is ongoing.

    Soil environmental conservation (improvement) in Southeast Asia is essential for ensuring water and food in the world, and the method needs to be customized according to the conditions of the target land. Among soil improvement, maintaining the microbiota in an appropriate range is a very complicated and meticulous work, but I believe that it can be completed by properly fermenting the organic waste and putting it into the soil.
