Precision farming, also referred to as precision agriculture, is a systematic approach to farm management that usually involves the use of information technology and satellite-based technology to identify, assess, and manage the spatial and temporal variability of agronomic parameters (such as crop health, soil, irrigation, pests or diseases, fertigation, etc.) within a field by applying the right amount of input at the right time and in the right place to achieve maximum productivity and profitability. Robotics, drones, GPS, automated hardware, GPS-based soil sampling, autonomous vehicles and variable rate technology are all examples of precision agricultural technology.
