The need of Agricultural Electronics

Sri Lanka is an Agricultural dependent country 28.2% of the population depends on Agriculture

The expected outcome is not achieved in Sri Lanka

Reasons

Farmers are isolated with knowledge about technology

Used to the ordinary methods

Lack of knowledge about the new methods

Hydrophonics Hydroponics(From the Greek words hydro, water and ponos,

labor) is a method of growing plants using mineral nutrient solutions,in water, without soil. Terrestrial plants may be grown withtheir roots in the mineral nutrient solution only or in an inert medium,

such as perlite, gravel, mineral wool, or coconut husk.from Wikipedia the free

encyclopedia

An effective method Can be practiced in a small area

Can be automatically controlled
