For the third trip to Hoober’s company, we learned a lot about precision agriculture. We talked about what does precision agriculture about and how it can be used in agriculture. Thought this trip, I saw how does technology are developing through these years, such as new tractors, combines and drone. These advanced equipments improve the efficiency of farmer’s work well. Especially the ability of drone is strong. It can scout a large area of field in a high efficiency. As it flied above the field, I believe that It can displaced the old ways of mapping and observing the field totally and found more agricultural problems. The most interesting part of this trip is that two students drive the tractor as a group, as well as the workers explained the operations and knowledge patiently. Overall, from this trip, I realized how technology promote the agriculture and how the technology develop fast now.
