Question

Hydroponics have been shown to be a successful technique for growing of plants. Yet most of the crops are still grown on land. Why?

Answer 1

Hydroponics:

Hydroponics is the technique of growing the plants in a nutrient medium without soil.


Disadvantages of hydroponics:

Even though hydroponics has been a successful technique for the commercial production of plants, many plants are still grown on land because of following reasons:

● The initial cost of setting up is very high. Only high quality crops that have high market value makes the cultivation economically feasible.

● It is a cumbersome process as frequent input of nutrients and air along with proper circulation is required.

● Such plants grown in laboratory conditions are susceptible to environmental conditions and require special care.

Cultivation of crops in soil:

Soil is a reservoir of nutrients. Although addition of manures and fertilisers are required at intervals, the techniques involved in cultivation on soil are comparatively less cumbersome. Thus, on a large scale, plants are grown on land instead of hydroponic technique.
