Proving the feasability of bamboo as an organic fertilizer by using it to cultivate rapeseed, advancing the Nanohana Project

Activity grant

Project Description

In recent years, bamboo has been growing wild in the mountain forests of Japan and it is having a negative effect on the growth of broad-leaved tree species crucial to maintaining forest functions. This project aims to develop regional resource-recycling initiatives such as using logged bamboo to cultivate rapeseed. Specifically, this involves: (1) testing bamboo chips as a fertilizer and verifying its effects on rapeseed cultivation, (2) turning bamboo charcoal into a fuel source, and (3) reducing bamboo damage, commodifying the fertilizer, and creating accompanying business models that develop regional agriculture and encourage farming collectives. This action is expected to encourage growth of broad-leaved tree species, enable the abundant growth of resources that produce economic benefits such as mountain vegetables, and also reduce traffic hazards and crime. Furthermore, if development of bamboo fertilizer goes smoothly, it will reduce the operating costs of fertilizer centers, encourage farming collectives and environmentally-friendly agriculture, and increase earnings for farming families.

Recent activity
The Nanohana Project grows rapeseed, collects waste cooking oil and produces biodiesel fuel. Core activities are as follows:
  • (1) Working with local elementary schools to develop an environmental education curriculum and holding lessons onsite
  • (2) Cultivating and selling high added-value 'Pure Na' rice
  • (3) Logging bamboo, which damages the landscape and causes traffic damage, and turning it into chips for use as a fertilizer
