Answer 1

The correct option is D All of the above

Hydroponics is the art of growing plants in absence of soil in a nutrient medium of defined concentration. It was initiated by Von Sachs. The technique is useful because plants can be grown in a defined medium. Pests can be avoided and plants can be protected from floods and drought etc. Also plants can be protected from various soil and water pollutants. In future, when pressure on land increases due to population growth, hydroponics will emerge as highly useful technique.
