It used to be mostly the army that used small,
unpiloted aircraft, called "drones". The little planes were very
costly. But as they have dropped in price more people have begun to use them.
The fast rate of development of computer
technology, image sensing equipment, satellite navigation and smart phones has
led to lower-priced drones. Researchers and developers have learned how to
build smaller and less costly drones. Nowadays, moviemakers are using drones to
film from the sky. Historians use them when they explore ancient buildings.
Rescue workers use them to look for people. And now farmers are also using them
to watch over their crops.
Romain Faroux is a French businessman, whose
father was a farmer. He believed drones could help farmers. He has helped
create a company which has developed a small drone that could be controlled by
people on the ground. It's called "Agridrone". It uses a special
sensor to examine crops. The technology used on the drone is similar to that
used on a smartphone -- except it has wings. A computer program directs
the drone to fly over the crops. The sensor on the drone records four
different-colored “bands” of sunlight that are reflected off the crops.
Jean-Baptiste Bruggeman is another farmer in France who is using a
drone. He says the drone flies over his crops at different times of the season
and provides a lot of information about his crops. The pictures taken by the
drone show him the exact amount of fertilizer the crops need. It also shows
exactly where the fertilizer is needed.
Romain Faroux says farmers use information
provided by the Agridrone to place fertilizer only in areas where it is needed.
This saves money and reduces pollution. Before they used the drones, farmers
would put the same amount of fertilizer everywhere. Drones also save time
because farmers can examine up to three hectares (英亩) in about a minute.
