Agriculture is one of the first spheres of the human economy. Over the years it has undergone radical changes, moving from bare-hand crop harvesting to using drones, robots, and other modern technologies that increase the farm’s efficiency and effectiveness. Today’s agriculture sector is responsible for feeding the whole Earth’s population and contributes to the GDP growth of many developing countries. All of these achievements would not be possible without the emergence and implementation of modern technologies, which are generally referred to as Smart farming or Agriculture 4.0. IoT sensors, machine learning and Big Data algorithms, AI, satellite imaging, robots, drones, and many more, today are helping farmers to increase their farms’ output.
