Our agriculture supports our rich food life. To produce good crops, various factors such as weather and soil are important, but the choice of fertilizer is also a crucial point. Currently, Japan's agriculture relies entirely on imported chemical fertilizers, and due to the impacts of the COVID-19 pandemic and the invasion of Ukraine, prices have been soaring. In response to this situation, the Ministry of Agriculture, Forestry and Fisheries announced the "Green Food System Strategy" in 2021, aiming for a 30% reduction in the use of chemical fertilizers by 2050 and a target of 25% of farmland to be organic farming without chemical fertilizers. The "Concentrated Bio Liquid Fertilizer" introduced in this article is a significant first step towards domestic production of organic fertilizers. Therefore, we spoke about the details of the concentrated bio liquid fertilizer project and the potential it holds. *For detailed content of the interview, please refer to the related links.
