Question

What is hydroponics? Give an application of this technique .

Answer 1

The practice of growing plants in nutrient-enriched water without soil is called soilless growth or hydroponics.

Application:

It is a special technique used in nutritional studies of plants. The plants are raised in large tanks made of borosilicate glass or natural polythene, containing a nutrient solution and are supported by wire netting. Tanks are provided with a solution regulating and pumping systems and are placed under controlled conditions. Iron is added as Fe-EDTA to keep the metal in soluble water (chelating agent or ligand). Because the plants are grown in large tanks, the process of soilless cultivation is also known as tank farming. Hydroponics is useful in areas having thin, infertile and dry soils.
