- It is a knowledge-based agricultural system that use technology to increase value and quality of farm's produce.
- Mostly found around densely populated urban areas

Definition
Characteristics
- Requires lots of capital inputs
- Have buildings to create conditions ideal for plant growth
- Daily operations carried out in or under controlled conditions
Purpose
- It enables maximum output on a small plot of land and is thus particularly important in countries with high population density and limited land area.
- Crops produced from high-tech farms help to reduce the dependence on the food imported from other countries.
Input
- Land. Very little land is required as crops are grown closer together in high – tech farms. Sufficient amounts of nutrients can be delivered and distributed evenly to the crops at regular intervals.
· Capital. Due to the use of the
latest technology, farm chemicals and investments in research and development, high – tech farms
require huge capital.
· Labour. High – tech farms are highly mechanized. This reduces the need for human labour.
Output
- High quality produce
- High profit and sales

Benefits
- More land and water conserved
- Less fertilizers and pesticides used
- Overproduction and wastage of resources minimized
- Less fuel used because crops need not be transported over long distance
- Minimize wastage of resources
Challenges faced by the countries
- High-tech farming requires high capital input.
- There will be a shortage of land for farming.

High-tech farming
Hydroponics
-from the Greek words hydro (water) and ponos (labour), a method of growing plants using mineral.- is a method of growing plants using mineral nutrient solutions, in water and without soil.
-Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, mineral wool or coconut husk.
Advantages
-No soil is needed
-The water stays in the system and can be reused - thus, lower water costs
-It is possible to control the nutrition levels in their entirely - thus, lower nutrition costs
-No nutrition pollution is released into the environment because of the controlled system
-Stable and high yields
-Pests and diseases are easier to get rid of than in soil because of the container's mobility.
Disadvantages
-The hydroponic conditions (presence of fertilizer and high humidity) create an environment that stimulates salmonella growth.
-Other disadvantages include pathogen attacks such as damp-off due to Verticillium wilt caused by the high moisture levels associated with hydroponics and over watering of soil based plants.
-Many hydroponic plants require different fertilizers and containment systems.
