Julius von Sachs (1860), a German botanist, demonstrated for the first time that plants could be grown to maturity in a nutrient solution without using soil. The technique of growing plants in nutrient solution is referred to as hydroponics. It is otherwise said to be soil-less agriculture. Commercially, the application bf hydroponics involves the production of horticultural and floricultural crops. This method may be used to increase yield of ornamental plants such as snapdragon, roses and vegetables such as carrot, radish, potatoes, tomatoes and lettuce.
Advantages of Hydroponics
- Provides the desired nutrient environment.
- Maintenance of the acid-base balance.
- Mulching, changing of soil and weeding are eliminated.
- Proper aeration of nutrient solution is possible.
