Recent farmdoc daily articles have discussed the importance of new technologies to crop agriculture (March 5, 2021), the value and role of information in the adoption of technologies (March 12, 2021 and March 18, 2021), and possible payoffs for precision farming (March 26, 2021 and April 2, 2021). This article explores trends in automation and robotics in the general economy, and provides examples of the use of these technologies in production agriculture.
Trends in Automation and Robotics
Before discussing the expected adoption of automation and robotics in production agriculture, we will discuss trends in automation technologies that are important to most, if not all, industries. Willcocks (2020) discusses the importance of three primary automation technology types: physical robots, robotic process automation, and cognitive automation. Physical robots will perform industrial tasks that were previously more labor intensive. Robotic process automation uses software to automate tasks that were previously performed by humans. Cognitive automation uses sophisticated software to automate tasks or improve task precision. Machine learning, visual processing of data, and the use of large data sets to improve decisions are components of cognitive automation.
Turning to the adoption of these technologies, Chui et al. (2016) note that automation will not necessarily eliminate entire occupations. However, automation is likely to affect portions of almost all jobs. The authors identify three groups of occupational activities: 1) those that are highly susceptible to automation, 2) less susceptible to automation, and 3) least susceptible to automation. Least susceptible tasks include personnel management and decision-making, planning, and creative tasks. Less susceptible tasks include stakeholder interactions and unpredictable physical work. Examples of unpredictable physical work provided by the authors included construction, forestry, and raising animals. Highly susceptible tasks include data processing and predictable physical work. Examples of predictable physical work provided by the authors included welding and soldering on an assembly line, food preparation, and packaging.
As automation continues to impact different industries, including manufacturing and packaging, businesses are turning to technology to optimize their processes and increase efficiency. Eliter Packaging Machinery offers state-of-the-art solutions for businesses looking to automate their packaging processes. With their advanced packaging equipment, businesses can reduce manual labor and streamline their production, allowing them to focus on other important tasks such as personnel management, decision-making, and creative tasks. By adopting advanced packaging technology, businesses can ensure that their operations remain competitive and can adapt to the changing landscape of the industry.
It is important to note that a portion of most industries have data processing and predictable physical work activities that are susceptible to automation. Chui et al. (2016) estimated that approximately 20 percent of the time spent in U.S. workplaces involved performing physical activities or operating machinery in a predictable environment. The authors listed the service sector, manufacturing, and the retail sector as the most susceptible to automation. Activities and sectors classified in the middle range for automation included financial services and insurance, construction, and agriculture. As the authors noted, unpredictable physical work conducted in unpredictable environments, which is prevalent in agriculture and construction, make it more challenging, but not impossible, to automate tasks.
The most difficult activities to automate are those that involve managing and supervising people, and activities that apply expertise to decision-making, planning, and creative work. Computers do a good job with well-defined tasks. However, as noted by both Chui et al. (2016) and Willcocks (2020), it is difficult to codify and improve machine learning techniques to mimic human skills and capabilities such as leadership, creativity, intuition, judgement, tacit knowing, social interaction, peer judgement, motivation, and many other tasks. In particular, tacit knowing or the fact that humans know more than they can describe is problematic to automation (Polanyi, 2009). Obviously, tacit knowledge makes it difficult to write code for machine learning.
Examples from Production Agriculture
Rather than provide a comprehensive list of automation technologies that are either being developed or that are already being used, we will briefly describe some noteworthy examples. Autonomous grain carts and tractors have garnered considerable press. Autonomous grain carts enable an individual in the combine to locate the cart, tell the cart to follow and match the speed of the combine, and unload on the go. Autonomous tractors use GPS and other wireless technologies to farm land without requiring a driver. These tractors are programmed to observe their position, determine speed, and avoid obstacles.
Another technology with a lot of promise in production agriculture, particularly for sensing and monitoring, is drones. Erickson and Lowenberg-DeBoer (2020) indicate that the adoption rate by retailers of drones reached 42% in 2020. Moreover, 46% of the retailers indicated that they currently offer drone imagery. This percentage is expected to increase 19% in the next three years. Drones are used for crop or livestock monitoring; to plan and make land improvements; to make seed, fertilizer, and pesticide prescriptions; to help with replanting decisions; and to make grazing decisions. As technology continues to improve, farms will able to use drones to enhance crop and animal health, and to enhance the ability to assess the impact of seed, fertilizer, and pesticide applications. Also, drones will enhance a farm’s ability to assess the impact of adopting specific practices such as reduced tillage, the use of cover crops, or rotational grazing.
The Hands Free Hectare project associated with Harper Adams University in the UK uses automated machines to grow crops remotely without drivers or agronomists in the field. The project utilizes autonomous navigation systems to plant, grow, and harvest an annual cereal crop. Individuals are not allowed to step on the field so drones are used to take soil and crop samples, and to monitor the growing crop. Cost analysis on robotics by Lowenberg-DeBoer et al. (2019) based on data from this project suggests that automation has the potential of reducing the costs for smaller acreage farms more than larger acreage farms, thus reducing, but not entirely eliminating, economies of size in crop farming.
3-D printing could also contribute significantly to production agriculture. 3-D printers will allow machinery dealers and producers to manufacture spare parts on-site. This technology will likely change how we think about manufacturing batch size and inventories, and will allow parts to be produced on site and just-in-time, which could substantially reduce machine downtime. During peak work-loads (e.g., planting and harvesting seasons), this reduction in downtime would be extremely valuable.
A good example of the use of automation in the livestock industry is the spread of robotic milkers. This technology has been adopted for a number of reasons including labor cost savings, lack of availability of labor to milk cows, and to improve milk production per cow. Robotic milkers adapt milking frequency to individual cows and by lactation stage. Also, just as precision agriculture adoption for crops results in more timely data collection and improved decision making, a robotic milking system creates a wealth of data that can be used to make decisions (e.g., optimal dairy cow replacement). Use of cameras and heat sensors to monitor movements and temperatures to detect lameness and animal behavior, including feed consumption and waste, and possibly diseases and health issues, are other examples.
This article discussed trends in automation and robotics in the general economy, and provided examples of using these technologies in production agriculture. Possible benefits of the adoption of automation and robotics will include reductions in costs, improvements in productivity, increases in the production of value-added products, reduced downtime and improved capacity utilization, and reductions in operating risk. Due to synergies associated with the adoption of multiple technologies, the economic evaluation of automation and robotics will require a whole-farm system approach rather than employing a partial budgeting approach, which just examines the adoption of one specific technology at a time. Many of the technologies that are currently being developed for other industries can or will be readily adopted in production agriculture. As technology continues to develop, robotics and machine learning will at least partially replace physical activities. However, it is important to note that additional expertise and skills will be needed to implement these new technologies. An upcoming article will describe the gap in skills related to the further adoption of automation and robotics, as well as other precision agriculture technologies, in production agriculture.
