Satellite Space-eye does not look like the
satellites of the 1980's. It has large wings that gather
solar power. The power is for the motor. It keeps the
satellite in the same place above the earth. All the big
farmers in the area have paid for the cost of Satellite
Space-eye.
Constanza is one of those farmers. His home
computer makes the connection with Satellite Space-
eye. He asks to see a picture of the field in the southwest
corner of his farm. The picture appears on a TV
screen. It is a picture of a green wheat field. Everything
looks fine, he then asks the computer to show the same
area, but in colours. .The colours show the different
temperatures in the field. He knows healthy wheat
plants will all be green. The TV screen blinks and a
beautiful picture appears. It has many shades of blue,
red, and green.
Constanza looks closely at the large red spot near
the middle of the wheat field. He knows that something
is wrong in the wheat field. The red colour means the
spot is warmer than its surroundings. It may be due to
lack of moisture or not enough nutrients in the soil.
Insects eating the wheat can also show a red spot.
Constanza tells the computer to tell him more
about the warm spot. The computer points out that the
problem is a shortage of nitrogen in the soil. He asks
the computer to predict the harvest if he adds the
fertilizer. He then tells the computer the current market
price for wheat. He also tells the price of the fertilizer.
He asks for a costing. He wants to know if it will give
him a profit to add the fertilizer. The computer gives
him the answer. Is it a science fiction? No, it is
happening now.
