Country shifts to automation as it faces an aging rural workforce and lack of young people interested in farming
Xinghua, China (Reuters) — A new combine harvester buzzes up and down a field in eastern China without a driver on board, chopping golden rice stalks and offering a glimpse of what authorities say is the automated future of the nation’s mammoth agricultural sector.
The bright green prototype was operating last autumn during a trial of driverless farm equipment as the government pushes firms to develop within seven years fully-automated machinery capable of planting, fertilizing and harvesting each of China’s staple crops: rice, wheat and corn.
That shift to automation is key to the farming sector in the world’s No.2 economy as it grapples with an aging rural workforce and a dearth of young people willing to endure the hardships many associate with toiling on the land.
Many western nations are taking similar steps in the face of such demographic pressures, but the sheer scale of China’s farming industry means the stakes are particularly high in its drive to automate agriculture.
“Automated farming is the way ahead and demand for it here is huge,” said Cheng Yue, general manager of tractor maker Changzhou Dongfeng CVT Co. Ltd., which provided an autonomous vehicle that was also used at the trial in the rice field in Xinghua, a county in the eastern province of Jiangsu.
However, the road to automation is long and littered with obstacles such as high costs, the nation’s varied terrain and the small size of many of its farms.
“I have heard of driverless tractors. But I don’t think they are practical, especially the really large ones,” said Li Guoyong, a wheat farmer in China’s northern Hebei province.
Most farms in his area are only a few acres in size, he said by phone.
To try to achieve its ambitious seven-year goal, Beijing is supporting trials of local technology across the country organized by the industry group Telematics Industry Application Alliance.
Members include state-owned tractor maker YTO Group, navigation systems producer Hwa Create and Zoomlion Heavy Industry Science & Technology Co. Ltd,, which helped develop the combine harvester used in the Xinghua trial along with Jiangsu University.
The next trials are slated for the northeastern province of Heilongjiang and for the hills around the southwestern city of Chongqing in the first half of this year.
Those come after a string of automated developments in the sector.
YTO developed its first driverless tractor in 2017 and is aiming to start mass production soon, depending on market demand, said Lei Jun, an executive at the firm’s technology centre, without giving a more detailed timeline.
Lovol Heavy Industry Co. Ltd. signed a deal with Baidu in April to apply the tech giant’s Apollo automated driving system to its agricultural machinery.
“China is expected to climb the autonomous technology ladder very quickly, mainly because Chinese companies can access the local navigation satellite system, which gives them an advantage over their international peers,” said Alexious Lee, head of China industrial research at Hong Kong brokerage CLSA.
He was referring to China’s Beidou homegrown satellite navigation system, a rival to the U.S. global positioning system.
Beijing has included agricultural machinery in its “made in China 2025” campaign, meaning the vast majority of its farm equipment should be produced at home by that time.
Semi-automated technology is already fairly common on farms in Europe and North America, but fully-automated tractors and combines have yet to be mass-produced anywhere.
However, with many Chinese farms still too small for a regular tractor, driverless ones that could be as high as four times more expensive at around $90,000 will be a long way out of reach for many in the short-term.
More than 90 percent of farms in China are less than three acres, while in the United States nearly 90 percent are larger than 12 acres.
“It is not about whether you have the product. It is about the entire system. It is about commercializing agriculture,” said Lee.
Analysts and industry officials said that the underlying trend would be for farms to get larger as ongoing reforms to land rights allow farmers to lease more space.
Sensors in equipment that help monitor crop conditions also need to be improved so that machines can adjust more quickly to different situations, said Wei Xinhua, deputy director of the school of agriculture equipment engineering at Jiangsu University.
China’s US$60 billion farm machinery industry has been burdened by overcapacity and low profit margins after a years-long subsidy scheme to promote mechanization in farming led to mass production of low-quality tractors. Analysts said it was too early to say how much the automated farming machinery sector could eventually be worth.
Automated farming machines are also useful in recording data on details such as volumes of fertilizers or other materials used in churning out crops, potentially helping farmers target consumers demanding higher-quality produce because some of that information could be included on food labels.
“Take a bowl of rice. I want to know exactly how it was planted, and how much fertilizer or pesticide was applied to it,” said Cheng at Changzhou Dongfeng.
