Robots with fingers designed to pick mature tomatoes, among the most delicate of crops. A Fitbit-like collar that monitors the wellbeing of a cow. Drones with sensors to identify dry areas of a field or discover crop production inefficiencies. “In 30 years, what we’re doing or seeing as innovative now will be viewed as tradition,” said Susan Duncan, associate director of the Virginia Agricultural Experiment Station at Virginia Tech University in Blacksburg.Science and technology will be core to the farming revolution, which teachers and agricultural leaders envision as including robots, temperature and moisture sensors, aerial images and GPS technology, alongside big data that affects everyone — suppliers, farmers, traders, processors, retailers and consumers.But agricultural educators and advocates are concerned about the future of agricultural education, given the industry’s broad needs and the lack of qualified job candidates.
