Keep in mind that no field is uniform and the yield potential varies tremendously within a single field. To get accurate counts the process should be repeated several times, not less than eight per field. Besides mapping your soils, fertility needs, disease prevalence and weed populations, GPS has moved into hearth and home. If your new car has a GPS receiver, there is a network of satellites tracking your route. If the car has a LoJack- transmitter, the signal that comes from this device can be used by the police if the car is ever reported stolen.
Pets can now get chipped.
In other words, a tiny microchip is inserted under their skin with a syringe so that if they are lost they can be tracked and found. With a new mandate from the Federal Communications Commission, all cellular phones sold next year must be able to identify their locations for emergency purposes. These signals will be received directly from the chips or through a Web network. Within a year, this same technology will be available in watches and necklaces that can be worn by children or Alzheimer s patients. In crop agriculture, GPS has already proven itself and rapid application of the technology is becoming more and more a reality.
