Precision farming, or precision agriculture, is a farm management system that utilizes information and technology. Its primary objective is identifying, analysing, and managing the spatial and temporal variability within fields to achieve the highest productivity, profitability, sustainability, and land resource protection while minimizing production expenses. Due to growing environmental concerns, agricultural management techniques must be altered to preserve natural resources such as water, air, and soil quality while maintaining economic profitability. "Site-specific management" refers to the appropriate application of inputs, such as chemical herbicides and fertilizers, in the correct quantity at the right time and place. Over a third of the world's food is produced with irrigation, thanks to the expansion of irrigation projects in recent decades to enhance productivity in the global food supply. However, the economic sustainability of old agricultural systems is being questioned by the market-based global rivalry in agricultural products, which calls for creating new and innovative production systems.
