Significantly reduced working time and water supply- Kubotake Mix’s “WATARAS” remotely and automatically manages the irrigation and drainage of paddy fields

What is “WATARAS field water management system”?

Kubotake Mix Co., Ltd.’s “WATARAS field water management system” is a system that can remotely and automatically manage the irrigation and drainage (water supply and drainage) of paddy fields and monitor water level and water temperature. by smartphone or personal computer.

This technology was primarily developed by the Agricultural Research Organization (Agricultural Technology and Food Industry Research Organization) by the “Next Generation Agriculture, Forestry and Fishery Technology” under the Program Innovative Innovation Strategy (SIP), “is a national level research and development project. It was.

By introducing “WATARAS”, not only remote valve opening and closing but also automatic water supply by timer setting and continuous flood automatically keep the set water level which can minimize water management labor. and waste. Significant reduction in water supply because water supply and drainage can be prevented * first To regconize.

Electric actuators (devices like valves) that can operate over the Internet are installed at the water supply valve and the drain port. Valve opening / closing instructions and user-made setting changes from a smartphone or personal computer are transmitted from a communication repeater installed near the field to the electric actuator via a radio Broadcast specific low-power (920MHz band) through cloud servers on the Internet. It is a mechanism of action.

Also, in the reverse route, the electric actuator automatically sends water level and water temperature data to the cloud server every 20 minutes, so the user can check the latest field data on the device. terminal at any time. ..

The installation differs depending on the location, but the important point is that it can be easily attached to the existing valve (also compatible with open channels and basins). In addition, the electric exciter is equipped with solar panels and batteries, so there is no need to prepare power sources in the field.

As for a communication repeater, since the wireless box and communication box are compactly integrated, it can be installed in a confined space and a communication repeater with a radius of 5 km (under good conditions, the antenna inside the actuator is outside). Up to 80 electrical actuators (40 standards) can be connected to be installed in (can be installed in). Since the system usage charge is set for each communication repeater, this is also a feature of “WATARAS” where operating costs can be reduced.

About 30% of total working hours * first Water management of paddy fields is reduced by “WATARAS field water management system”

“I was skeptical at first, but it got easier anyway,” he said with a laugh and performed “WATARAS” at the Chiba Prefecture Smart Agriculture Introductory Demonstration Project in April 2018. Mr. Masahiro Takahashi, a Kaneta farm in Yamatake city, Chiba prefecture, who experimented.

Mr. Takahashi grows 6 types of sticky rice and 3 types of sticky rice in a field of 55 hectares (11.8 Tokyo Domes) and about 250 sheets. In recent years, the number of people taking over fields from abandoned farmers has increased, and we manage many fields in the suburbs. It takes a lot of effort to manage the water in those fields, and it takes a day and a half on a scooter to see everything, and the total travel distance is said to be 100km.

The field where “WATARAS” was installed is also 9km straight from the house and involves a remote control, “While you are shaving in another field, give instructions on how to put shaving water with a smartphone. For example, it’s impressive that the water is clear after two days, “he said.” The water level can always be checked on a smartphone, so daily patrols are no longer required. ” ..

[Kết quả thử nghiệm của Tổ chức Nghiên cứu Nông nghiệp cho thấy thời gian làm việc cần thiết cho việc quản lý nước giảm khoảng 80% và lượng nước sử dụng giảm 50%] * first Takahashi nodded, “That’s really true.”

“You might think you’re just looking around, but water management makes up a large part of the work of the rice plant, and if it’s not noticed, the weeds will increase and a vicious cycle happens like this. herbicide bridge. The biggest contributor is the time spent that can be spent on follow-up jobs like mowing lawns and getting dressed. “- Mr. Takahashi talked about the effect of reducing labor in water management.

In addition, Mr. Takahashi said that it is also effective in reducing the amount of water used. “If you set it to a constant water level, it automatically keeps the set water level, eliminating unnecessary water supply and drainage for the ground temperature on hot sunny days. Although it is flushed to lower the level. water but not be dropped or spilled With “WATARAS”, the water stops at the set water level, inconvenient to other water users.If possible, if the district improves the land, JA, the main Government, etc. can actively introduce “WATARAS” throughout the region, I think water resources can be effectively shared. “

“In the past, patrol work was done visually and according to experimental rules, but by inserting” WATARAS “you can visualize the scene and test it on your smartphone, so when you feel it is different from normal.I went to see the field.Also, since I can keep the water level as set, I can stop the operation of the jumbo tanishi and reduce the feeding damage, and no water leakage due to mogura intrusion. Since you can see the aperture within your reach, you can capture leaks you don’t notice with numerical values. “- Mr. Takahashi said that the This introduction is effective in addition to reducing water management workforce and water consumption.

Finally, when asked about the expansion, “I would like to introduce little by little about each plot of the field, which has seven plots, and want the producers around me to know about“ WATARAS ”. Of course, the government will help. I would be very grateful if you could, but since the number of agricultural workers is decreasing, the demand for this system will increase in the future … “Takahashi, who is expecting it to be widely used. in the area, say.

Kubota Group provides cultivation support services “KSAS (Smart Agricultural System Kubota)” and IoT service “KSIS (Intelligent Infrastructure Systems Kubota)” in the field of water environment. According to Kubotake Mix, they will collaborate with “WATARAS” in the future.

It is the trend of the era where fields will continue to accumulate among the top farmers.In such an environment, about 30% of the total working hours of wet rice cultivation. * first It can be said that there is a lot of expectation for the “WATARAS field water management system” that could reduce water management labor occupying acreage.
