Paid Rental of 'Magnetic Sensor' to JA Zennoh Nagano Starts April 1 to Shorten Soil Analysis Time: Providing Detailed Soil Data Faster Than Conventional Methods

Henry Monitor Co., Ltd. (Headquarters: Suwa City, Nagano Prefecture, CEO: Takashi Komatsu), which provides a "soil analysis service using magnetic sensors," has started a paid rental service of its self-developed desktop magnetic sensor (HMDT-01) to the National Federation of Agricultural Cooperative Associations Nagano Prefecture Headquarters (JA Zennoh Nagano) from April 1, 2026. In order to shorten the time required for conventional soil analysis, we have been building a basic database and developing equipment since 2024. For this service, JA Zennoh Nagano will "test-introduce" it this time, and demonstration experiments for full-scale introduction will be developed in the future.

[Background]

Recently, in the agricultural sector, soaring prices of chemical fertilizers and a declining labor force have become major issues.

In response to this issue, our company has proposed a solution that simplifies agricultural land management by developing a device with unique technology that allows appropriate field management to be performed in a short time. Through this solution, we hope to improve crop yields and quality, leading to increased profits for farmers.

[Features and Points of the Service]

1. Environmentally friendly device

Soil analysis can be performed without using any chemicals required in conventional analysis methods.

2. Immediate calculation of CEC (Cation Exchange Capacity, *1) and bases (lime, potash, magnesia, etc.)

With measurements by this device and estimation formulas using AI, CEC *1 and bases, which conventionally took several weeks, can be obtained.

3. Eco-design operating only on USB power

It can be powered simply by a USB connection to a PC, tablet, etc., allowing anyone to easily perform measurements.
