Precision agriculture is a new trend in the development of agriculture in the world today, which applies the most advanced technology to agricultural production to achieve the goal of scientifically and reasonably utilizing agricultural resources, improving agricultural economic benefits, and reducing production costs. On the one hand, it clarifies the spatial variation of soil properties and productivity within the field, and on the other hand, it determines the production goals of crops, carries out systematic diagnosis, optimization of formulas, technical assembly, and scientific management, mobilizes soil productivity, achieves equal or higher income with the least or most economical input, improves the environment, efficiently utilizes various agricultural resources, and achieves economic and environmental benefits. Precision agriculture is the comprehensive application of technologies such as Global Navigation Satellite System (GNSS), Geographic Information System (GIS), Remote Sensing (RS), and Computer Automatic Control System to produce a series of new products including autonomous driving, yield measurement, flow control, variable control, seeding control, and information sharing. This improves the standardization of agricultural production, promotes efficient land use, and maximizes yield.
