Hydroponics system
• Solution culture is being used for rasising flowers and vegetables at home. This soil less production of plants is called hydroponics.
• Plants are raised in small tanks of concrete or metal. The tanks are covered over by wire netting or gauze. They are filled up with a water solution containing appropriate quantities of all mineral elements. The solution is changed from time to time. There is a mechanism for aeration and circulation. pH is checked and correction are made regularly. Iron is added as Fe-EDTA otherwise it gets precipitated, especially in alkine pH. The agent which keeps metals in the soluble state is called chelating agent or ligand. EDTA (ethylene diamine tetra-acetic acid) is one such agent. Fe-EDTA complex is called chelate.For More Biology Doubts visit main page of Physics Wallah.
• As soon as the plants enlarge they are tied to the roof of the chambers by means of strings.
• Hydroponics is useful in areas having thin, infertile and dry soils. They conserve water. Additionally hydroponics can regulate pH optimum for particular crop, control soil borne pathogens, avoid problems of weeding and obtain consistently better yield. Out of season vegetables and flowers can also be obtained.
