Which concept relies on GPS and remote sensing to manage variability in crops?

• A. Precision Agriculture
• B. Biotechnology
• C. Guarding
• D. Fire Extinguishers

Answer: (A)

Precision agriculture uses GPS and remote sensing to manage variability within fields. In a single field, soil fertility, moisture, and crop vigor aren’t uniform, so treating the whole area the same way wastes inputs and can limit yields. GPS gives exact location data so farmers can create field maps that show where conditions differ, while remote sensing—through drones or satellites—provides real-time information on crop health and stress by analyzing reflected light or thermal data. That combination lets you apply inputs like water, fertilizers, and pesticides at varying rates in different zones, tailoring management to each area’s needs. The result is more efficient input use, lower costs, and better yields with less environmental impact. The other options don’t fit because biotechnology deals with genetic modification, and guarding or fire extinguishers are unrelated to managing crop variability with sensing and location data.
