High Tech Farming :
Hydroponics
What's hydroponics ?
- a technique of growing
plants (without soil) in water
containing dissolved nutrients
-Usually takes place in or around densely populated
urban areas where land is limited & costly (Eg:
Singapore)
-Singapore can increase self-sufficiency so that it
can reduce its dependence on imports.
Inputs
Physical:
-Sunlight/Shade
-Land
Human:
-High capital inputs (Farms have special buildings such as
shelters and greenhouses to crate conditions ideal for plant
growth-installation of new technologies like computers &
automatic devices are needed)
-High technology
-Knowledge driven
Processes
- Germinating seeds in a dark room
- Transplanting to growing troughs
- Adding nutrient solution using computers
- Monitoring plant growth using computers
-Harvesting (manually)
- Packaging and refrigerated transport
Outputs
-Produce a variety of other
outputs that are generally of high
quality.
-Includes vegetables, flowers,
fruits, eggs, dairy products,
ornamental fish for both local and
overseas markets.
Challenges Faced
-High capital investment
-Shortage of trained workers (educated workforce
but people are unwilling to work as high tech farmers)
-Competition from imported fruits and vegetables,
discouraging high-tech farmers from expanding their
operations
