Define "precision agriculture."

Precision agriculture refers to the use of technology and data analysis to optimize farming practices by managing field variability. This approach involves the use of tools such as GPS, sensors, and data analytics to monitor and manage the different conditions within a field, such as soil composition, moisture levels, and crop health. By applying resources more efficiently, farmers can enhance productivity, reduce waste, and make informed decisions based on real-time data.

The emphasis on managing variability is crucial as it allows farmers to apply specific treatments where they are needed rather than uniformly across an entire field. This technological integration can lead to improved crop yields, lower input costs, and reduced environmental impact, aligning with sustainable agricultural practices. In contrast, the other options outline various farming techniques or methods that do not incorporate the use of advanced technology or data-driven approaches that are characteristic of precision agriculture.
