“Water management” is the pain of rice farmers To automate by smartphone application
A year of a farmer cultivating rice is extremely busy, starting with sowing and sowing, transplanting rice to the ground and then harvesting. In particular, the work that consumes a lot of time, about 6 hours a day, for a period of 4 to 5 months is called water level and temperature management (water management) in rice fields. However, the mechanization of water door opening and closing is not good.
Under these circumstances, a joint venture has developed a service that reduces the burden on aging manufacturers by remotely managing water through an app on a smartphone.
Mr. Gotoku Shimomura, from an IT company, started business in Toyama prefecture in 2013. We have developed a service that helps to reduce the burden on aging manufacturers by remotely managing water through application on a smartphone. Toyama Prefecture is one of the best rice fields in Japan, where rice fields make up 90% of the total cultivated area, and Mr. Shimomura was born the eldest son of a local rice farmer.
In conventional water management, water level and temperature are controlled by inserting and removing wooden boards installed in irrigation canals according to growth phase and temperature. “It’s a simple task but has a huge impact on results,” Shimomura said. For example, if the field temperature is increased due to inadequate water management, it may cause cracking inside the rice plant, “cracking”, or the yield may drop due to weed growth leading to a decrease in productivity. ..
“The more veteran farmers that make delicious rice, the more they are attached to water management,” Shimomura said. However, deciding when and how much is appropriate depends on experience and intuition, and it is difficult to pass on the know-how to the next generation.
Automatically manage water level and temperature with simple operation Use for increased profit
Also, be sure to look around even in bad weather and at midnight, there is a risk of an accident. Toyama prefecture, which has thick and prone to fast flowing agricultural water canals, is said to have “the worst water accident rate in Japan” (Mr. Shimomura).
Mr. Shimomura has developed an intelligent rice service for rice farmers, “gate 02”, to solve problems on the spot with technology. By installing an IoT device equipped with a SIM card and water level sensor on the paddy field, you can capture and adjust the water level and temperature in the field with just one simple operation from the smartphone app. smart or PC.
Since the water gate can open and close automatically, and the timer can be set from anywhere via the Internet, there’s no need to travel around midnight, early morning, or even in bad weather. It can also be used to automatically open the door and lower the water temperature when certain water temperature is reached. Crops data can be managed in the cloud, which can be expected to reduce time costs and improve management efficiency by accumulating information.
When I first explained the project to the farmers, Mr. Shimomura’s response was astonishing.
“No one doubted that water management took so long in the first place. No one thought it was a task that should be shortened.” Taking advantage of the foundation of confidence, while at the same time resolving the resistance of conservative peasants with a polite narrative, attracting introductory labor as creating a new source of income in free time. Word of mouth spread and the number of requests gradually increased.
Currently, a total of 100 units have been installed from Hokkaido to Kyushu. This is the first Hokuriku company to be adopted as a KDDI startup support program.
“The use of farmers in their 30s and 40s, such as those who want to scale, is increasing,” Shimomura said. I hope that they can effectively use their time spent on water management and increase their income. ..
100 years later to eat delicious rice
Data accumulation is also expected to be used in the future when forecasting climate change.
“When warming occurs, there is a risk that the current standard varieties such as” Koshihikari “, which are not well heat tolerant, will not grow. Although recommended varieties are switching taking place in each province, only the farmer’s experience and intuition. If you rely on it, you can’t apply it to new varieties.
However, if a device such as “port axis 02” is widely disseminated nationwide, it will be possible to accumulate data on new fertilizers and water volumes and pass on the know-how to the next generation.
“If you leave the wisdom of the professional in the data, you can deploy it horizontally. Perhaps a complete amateur could suddenly produce 80 quality rice points on a large scale. How to control the step of the production sector with AI I think it is possible to manage water with a higher quality than the human hand I want to create a future where we can continue to eat rice 100 years from now, “Shimomura said. “Toyama is the birthplace of the rice chaos. We want to revolutionize the rice production site through Toyama’s technology,” he said.
* “Paditch gate 02” introduction fee is 120,000 yen for equipment + 1,100 yen per month for communication.
Speakers in the agriculture industry, including Tomomasa Oikawa, representative of Agricultural Research Institute Ltd., will talk about “the future of data usage where smart agriculture will change.”
