Changing the World's Soil with Japanese Microbial Technology, Regenerating the Earth's Future. Resahl Kousan Launches 'U.S. Expansion Project'

Resahl Kousan Co., Ltd. (Headquarters: Saitama City, Saitama Prefecture; President: Hayato Iikawa), which supports sustainable agriculture and horticulture with the power of microorganisms, is officially launching a project to enter the U.S. market with its core product, the microbial material "Kalus NC-R," as it celebrates its 50th anniversary. In line with this, the company has started a project on Japan's largest crowdfunding site, "CAMPFIRE," to accelerate efforts to establish a verification and sales system in the U.S. and reduce environmental impact.

Currently, agricultural sites around the world are facing various challenges related to soil preparation.

Over-reliance on chemical fertilizers and continuous cropping have led to deteriorating soil conditions, increasing the prevalence of fields susceptible to diseases and pests. The disposal of large amounts of crop residue (plant waste) after harvest is also a major issue.

Originally, fallen leaves and plant residues were part of a cycle, returning to the soil to nurture the next generation of life. However, in modern times, they are often incinerated or discarded as "waste."
In response to this soil degradation, there is an increasing reliance on more chemical fertilizers and pesticides to supplement nutrient deficiencies.

However, this accumulation disrupts the balance of soil microorganisms, leading to problems such as soil hardening and poor drainage, which weakens the soil's natural strength.
As a result, soil degradation has led to an increase in fields where plants and crops are prone to diseases and pests, significantly impacting the balance of the global environmental cycle. Our "Kalus NC-R" addresses this global structural issue by rapidly converting crop residues on-site into high-quality nutrients and restoring soil microbial diversity. We aim to introduce this technology, which has gained wide support in Japan, to the U.S. market, the world's largest agricultural powerhouse, and propose new possibilities for future agriculture and horticulture through soil environment improvement.

In recent years, the idea of "returning to the soil" has also begun to spread beyond agriculture into the world of home gardening.
Many people resonate with this new approach to soil preparation, which involves using the power of microorganisms to cycle what was previously disposed of as waste—fallen leaves, dead grass, vegetable scraps, and used potting soil—into nutrients for the next plants.

We have received numerous comments from users of Kalus NC-R, such as:
"I've come to see parting with plants, which I used to just dispose of, as part of a cycle."
"Every time I return something to the soil, I feel a connection to the next life, and soil preparation itself has become enjoyable."
"My perspective on fallen leaves and dead grass in my garden has changed. I now think about how to utilize them, not just throw them away."

Our company will now spread the culture of returning to the soil, which is beginning to grow in Japan, to the world, along with the power of microorganisms.
