Precision farming practices are now being adopted in order to sustainably feed the world's rapidly expanding population while managing resources effectively. Internet of Things (IoT), artificial intelligence (AI), information and communication technology (ICT), and big data analytics are all used in digital farming to improve precision farming techniques. By making accurate decisions at every step of the food production and supply chain, from the selection of the variety to be planted and the preparation of the land to the marketing of the produce, digital farming permits novel approaches to crop production. This article discusses how digital technologies can be used to improve conventional farming methods.
