Murata Manufacturing is promoting measures to address salinity impact to agricultural land by conducting field trials utilizing a soil monitoring system that makes it possible to visualize the condition of agricultural land in the Mekong Delta in collaboration with Can Tho University, a national university of Vietnam. The initiative is part of “Studies on Sustainable Soil Uses” (hereinafter referred to as “the Project”), based on an agreement between the governments of Japan and Vietnam to provide ODA (Official Development Assistance) in support of measures to address the problem of salinity impact to agricultural land.
Murata has been conducting the Project since 2017 in collaboration with Can Tho University, which possesses deep knowledge of agricultural and environmental research in the Mekong Delta. The Company is using compact sensor units that draw on its know-how and expertise in the fields of electronic components, circuit design, and software design to measure the condition of agricultural land and channel water with high precision. Combining these observations with independently developed monitoring tools, we can visualize and analyze the environmental conditions with a view. It contributes to the implementation of IT in agriculture in the Mekong Delta region by preventing salt damage to rice paddies and orchards, ameliorating salt and sulfur contamination of agricultural land and water channels, and creating a mechanism to comprehensively manage fertilizers, crops and irrigation systems.
The wireless transmitter-receiver system consists of a gateway, a router, and several sensor nodes. Each sensor node is made up of a transmitter and three sensor units to measure the soil, field and channel water quality, and the sensing data is accumulated in the cloud.
The Key Features include:
- A compact approximately 13cm sensor unit equipped with three sensors for measuring two types of electrical conductivity*4, temperature and moisture content
- High-precision analysis of conditions utilizing a sensor incorporating a uniquely shaped sensor element and a proprietary algorithm
- Over a year of continuous operation on three size AA batteries
- IP68 dust and water resistance and reliable rustproofing enabling prolonged use in harsh environments
The Project began with a three-year plan from 2017 utilizing know-how developed in the restoration of agricultural land based on monitoring of the salt content condition of farmland damaged by the tsunami triggered by the Great East Japan Earthquake of 2011. In addition to Soc Trang and Ca Mau Province, where the monitoring system was initially introduced, in October 2018 we deployed the system in other four locations in Ben Tre and Kien Giang province. Through joint researches with many research institutions, Murata will continue to make efforts to realize global SDGs by utilizing its unique sensing and wireless technologies.
