Precision agriculture

Definition

Precision agriculture is a modern farming practice that utilizes technology and data analysis to optimize crop yields, resource use, and sustainability. This approach involves the use of tools like GPS, sensors, and drones to monitor field variability and make informed decisions about planting, fertilizing, and irrigating. By precisely managing inputs based on specific conditions, farmers can enhance productivity while minimizing waste and environmental impact.
