C. READING

IX Read the passage.
Over a million people working in America’s fields, and far more globally, are about to
face competition from workers who never get tired or ask for a living wage.

As field robots have gotten cheaper, a steady stream of farm jobs are being automated.
Lettuce weeding is one of the first where the cost of robots now matches human labor.
Weeding lettuce is slow, expensive, and potentially dangerous due to chemical exposure.
Farm workers must spray individual weeds from a pesticide-filled backpack. Automated
systems like the one designed by Danish firm F. Poulsen Engineering replace this with
mechanical weeding and computer vision to distinguish between crops and pests. The
company says it can do the job much faster and at no extra cost.
Robots will likely make inroads fastest in areas where the labor is backbreaking, and peak
harvest times create a short supply of workers. Most robots have been built for specialized
tasks: grapevine pruners, lettuce thinners, strawberry picking and cow-milking robots. But
corn and other commodity crops are already taking advantage of economies of scale to get
ahead of the cost curve. Large corn farmers in the US are buying features like self-steering
tractors to save money. Even though the technology isn’t expected to reach price parity with
human labor until 2020 for most farmers, about 10% of US farmer have adopted the
technology because of their scale.
