A Review on Precision Agriculture: An Evolution and Prospect for the Future

A farm management system that uses information and technology to identify, analyze, and control the temporal and spatial variability within a field is known as precision farming or precision agriculture. Its goals are to maximize productivity and profitability, preserve the land resource, and minimize production costs. The public's growing environmental consciousness is forcing us to alter agricultural management techniques in order to maintain economic profitability while preserving natural resources like water, air, and soil quality. The application of inputs (such as chemical pesticides and fertilizers) in accordance with the proper amount, timing, and location. "Site-Specific Management" is the term used to describe this kind of management. With over a third of the world's food now requiring irrigation for production, the productivity increase in the global food supply has depended more and more on the expansion of irrigation schemes in recent decades. The overall economic viability of traditional agricultural systems is being challenged by market-based global competition in agricultural products, which calls for the creation of new, flexible production systems.
