The correct answer is D) All of the above.
Precision farming is a farming management concept based on observing, measuring, and responding to variability in agricultural production. It aims to optimize the production and efficiency of agricultural production systems.
GPS (Global Positioning System) is a satellite-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth. GPS is used in precision farming to track the location of farm equipment, monitor crop growth, and apply fertilizer and pesticides more precisely.
Sensors are devices that detect and measure physical quantities and convert them into signals that can be read by a computer. Sensors are used in precision farming to measure soil moisture, temperature, and nutrient levels, as well as to monitor crop growth and pest infestations.
Drones are unmanned aerial vehicles (UAVs) that can be used to collect data on crops, soil, and other agricultural conditions. Drones are used in precision farming to map fields, identify areas of crop stress, and apply pesticides and fertilizers more precisely.
Precision farming can help farmers to increase crop yields, reduce costs, and improve the sustainability of their operations.
