4. What is hi-tech farming?
Uses advance scientific methods to improve crop yield or to control the environment in which crops are grown and often automation and computerization are used to reduce the input labor.
Consist of hydroponics and aeroponics, not grown in soil.
Temperature at which crops are grown and amount of the water are controlled by computer.
Highly efficient and productive as well as environmental friendly.

5. Who and where practices hi-tech farming?
Developed countries that have limited land.
Countries that practices Hi-tech farming are: Singapore, USA, Japan and so on.

6. Why do they practice hi-tech farming?
That country have limited lands
Higher yields can be obtained
Clean environment
Organic, no pesticides
Easy hiring labour

7. Methods and Techniques
Circulating system
Nutrient film technique
Deep flow technique (pipe system)
Non-circulating system
Root dipping technique
Floating technique
Aggregate system
Hand Bag technique (open system)
Grow Bag technique
Trench or Trough technique
Pot technique
Aeroponic technique
3 Methods
9 Techniques

8. Advantages of hi-tech farming
Big lands are not necessary.
No soil required
Clean working environment.
No soil borne diseases.
Off-season production is possible.
Easy to hire labor as hydroponics system is more attractive and easier than cultivation in soil.
Water wastage is reduced to minimum.

9. Disadvantages of hi-tech farming
• Higher expenditure.
If the electric pump fail, the plants will die easily.
• Considering the significantly high cost, the soil-less culture is limited to high value crops of the area of cultivation.
• A large-scale cultivator may have to purchase instruments to measure pH and EC of the nutrient solution.
• Energy inputs are necessary to run the system.

10. Summarizing of main points
Soiless culture, which also means that they use mineral nutrient solution instead of soil.
Solution in which pH, temperature, and nutrient concentrations are Controlled by computers.
Environmental friendly.

This website is very useful, it tells us very single thing about hi-tech farming, like techniques of hi-tech farming, history of hi-tech farming, advantages of hi-tech farming and so on.
This website is also good, it provides us a lot more information about hi-tech farming.
This website is also quite useful to m because I found those information I need.
