isn’t place for humans and crops in this world”
It is true, with increasing population nearing a staggering number
of 7.5 billion the world is getting smaller for plants and animals. Human
beings are finding it difficult to find shelter and food supplements at the
same time. The current farming techniques are not proving sufficient for the
food needs of the world; hence researchers are looking at more productive
means. One of the best alternatives found is a method called Hydroponics.
Hydroponics involves the growth of plants without the use of
conventional soil. As an alternative to soil, a nutrient rich solution
consisting of water and minerals are used. This solution provides the required
supplements for the roots. The greatest advantage of this method is that plants
that grow in particular conditions can be grown globally.
How does Hydroponics work?
It is typical for a plant to take the support of the soil to grow
and establish a firm grip to remain upright. Further, it is the soil that
provides a plant or a tree with nutrients. Hydroponics is developed based on
this formula and provides nutrients, support and uprightness with the help of nutrient
rich solution. The solution is rich with ionic compounds that provide
sufficient nutrients for the plants.
As the method involves the use of solution that needs to be made
available to the plant, it can be done in many ways:
The plant can be placed in
inert substances and allow periodical flow of solution to the roots.
The plant can be placed in
inert substances and allow the solution to be sprayed in the form of mist.
Ø The plant can be placed on a sloping film to allow the solution to
flow over the roots.
These current methods of Hydroponics can be
automated so that the farmer need not check with the plants more often.
Advantages of Hydroponics
The process involved with hydroponics is
similar to creating a virtual reality to the plants so that they can grow
faster. The nutrient solution, heating equipment, artificial lights, etc. used
in the method helps the plant to grow faster.
One can save a lot of water with this method.
The water used can be recycled for many times and in comparison to regular
farming, only 10% of water is used for a harvest. The same goes with the
fertilizers used and only 25-30% of the fertilizer is used in comparison to
conventional farming. The plants are free from attack of insects, pests,
rodents, fungus, etc. as the environment is controlled and there is not stock
of water. Therefore, there is NO NEED OF PESTICIDES.
Transportation costs can be cut to a minimum
as the Hydroponic farms can be established near the place of selling. In
addition, a single crop can be repeatedly grown with the solution as there is
no soil involved.
prove to be the best solution for the growing food needs and organic
development of crops. With proper care and understanding, a farmer can produce
more food in considerably less space and help with the sustenance of the
