Yonezawa Farm's Bioactive Water Project History (Yonezawa City, Yamagata Prefecture) - October 1994

#### 1990s
In 1994, **Yonezawa Farm** in **Yonezawa City, Yamagata Prefecture**, launched the "Bioactive Water Project" with the goal of environmental conservation and sustainable agriculture. The technical foundation of this project was the use of **BMW technology (Bio Microbials Water)**, which ferments livestock manure to produce **bioactive water**. This bioactive water is used as **organic fertilizer** to improve soil in local farmland and increase crop productivity.

At Yonezawa Farm, approximately **10,000 liters** of bioactive water were produced annually and supplied to local farmers. This technology allowed efficient supplementation of essential nutrients such as **nitrogen** and **phosphorus** in Yonezawa's farmland, greatly reducing the use of chemical fertilizers. The introduction of this project led to a reduction in environmental impact and increased agricultural yields across the region.

#### 2000s
In the 2000s, Yonezawa Farm's bioactive water project expanded, with strengthened collaboration with **JA Yamagata**. This allowed the supply of bioactive water to not only farmers around **Yonezawa City** but also agricultural workers throughout Yamagata Prefecture. During this period, the annual production of bioactive water increased, surpassing **20,000 liters** per year.

Additionally, this technology improved the **microbial environment** of the soil, leading to further increases in crop yields. The benefits were particularly evident in crops such as **rice** and **vegetables**, contributing to the revitalization of the local agricultural economy. The project also reduced the costs of **agricultural waste disposal** for local farmers, lowering agricultural production costs.

#### 2010s
During the 2010s, the Yonezawa Farm project saw technological advancements and was widely adopted both within and outside the region. During this period, the project deepened collaboration with more companies and research institutions, including **JA Yamagata** and the **Agricultural Technology Center**, improving the efficiency of bioactive water production and application.

At Yonezawa Farm, in addition to improving soil, there was a strong focus on increasing agricultural productivity. The use of bioactive water reportedly increased the yields of key crops such as **rice**, **tomatoes**, and **cucumbers** by an average of **20% or more**. During this time, the project received high praise from agricultural workers inside and outside Yonezawa, leading to the adoption of this technology in other farms.

#### 2020s
In the 2020s, Yonezawa Farm's bioactive water project has continued to expand. The production capacity of bioactive water has increased significantly, with over **50,000 liters** produced annually, extending its use beyond Yonezawa to the entire **Yamagata Prefecture**. Additionally, the introduction of an **AI-based agricultural management system** has improved the efficient application of bioactive water.

Furthermore, efforts to minimize environmental impact while maximizing crop growth have gained international attention. Yonezawa Farm is also looking at technology transfer to other regions, including collaborations with agricultural technology research institutions in **Southeast Asia** and **Europe**. As a model for sustainable agriculture, Yonezawa Farm's project continues to contribute to both regional economic development and environmental conservation.

Yonezawa Farm is highly regarded within and outside **Yamagata Prefecture** as a leader in **sustainable agriculture** and **environmental conservation**, and it aims to further advance environmentally friendly agricultural technologies in the future.
