A long time ago, farming was strenuous and intensive. Mules slogging the fields is now a thing of the past and now, tractors plowing them are developed. As time passes, the use of these tractors began to increase and manpower needed for the fields declined.
With the advent of the GPS since 9 years ago, people have been able to do more, with less. Things have become more efficient with the implementation of the GPS in the fields. Farmers instead of needing 5 trips, now only need 1 trip to get the seeds planted.
Fields are sprayed, and with the help of GPS, the farmers will know where and what is sprayed with insecticide. Yields too have increased. Farmers admit that although it is more expensive, but in the long run it is more cost effective. Furthermore, it helps to relieve stress by spending less time out in the fields. Checking the difference in yields in different parts of the farm and being able to measure the soil salinity in the various sections is just some of the things the GPS can provide. A GPS costs $25,000 and with the tractor, a total of $250,000.
