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 factors within the field, such as soil type, moisture, plant growth, and pest or disease presence. This is accomplished through a variety of technologies, including sensor technology, GPS, and satellite data.
Sensor technology is used to collect data on the field conditions, such as soil moisture, temperature, and pH. This data can then be used to make decisions about irrigation, fertilization, and pest control.
GPS is used to track the location of farm equipment and livestock. This information can be used to optimize the use of resources, such as fertilizer and pesticides.
Satellite data is used to create maps of the field conditions. These maps can be used to identify areas that need irrigation, fertilization, or pest control.
Precision farming can help farmers to increase yields, reduce costs, and improve the sustainability of their operations.
