The document discusses hydroponic technology as a soil-less farming method essential for addressing challenges posed by urbanization, climate change, and declining arable land. It covers the advantages and disadvantages of hydroponics, including efficient resource use, higher yields, and high initial costs, while emphasizing its future potential in feeding populations and supporting space exploration. A case study illustrates a successful hydroponics business, demonstrating the technology's viability and the need for government support to enhance food security.

4.  Due to rapid urbanization and industrialization as well as melting
of icebergs (as an obvious impact of global warming), arable land
under cultivation is further going to decrease.
 Frequent drought conditions and unpredictability of climate and
weather patterns, rise in temperature, river pollution, poor water
management and wastage of huge amount of water, decline in
ground water level, etc. are threatening food production under
conventional soil-based agriculture.
 Under such circumstances, in near future it will become
impossible to feed the entire population using open field system
of agricultural production only.
 Naturally, soil-less culture is becoming more relevant in the
present scenario, to cope-up with these challenges.
 In soil-less culture, plants are raised without soil.
 Improved space and water conserving methods of food
production under soil-less culture have shown some promising
results all over the World.

6.  Soil-less culture mainly refers to the techniques of Hydroponics.
 The term Hydroponics was derived from the Greek words’ hydro’
means water and ‘ponos’ means labour.
 It is a method of growing plants using mineral nutrient solutions,
without soil.
 Terrestrial plants may be grown with their roots in the mineral
nutrient solution only or in an inert medium, such as perlite,
gravel, or mineral wool.
 Hydroponics is the technique of growing plants in soil-less
condition with their roots immersed in nutrient solution.
 This system helps to face the challenges of climate change and
also helps in production system management for efficient
utilization of natural resources and mitigating malnutrition.
 In India, Hydroponics was introduced in year 1946 by an English
scientist, W. J. Shalto Duglas and he established a laboratory in
Kalimpong area, West Bengal.
 He has also written a book on Hydroponics, named as Hydroponics
The Bengal System.

9.  In 1929, William Frederick Gericke of the University of California at
Berkeley began publicly promoting that solution culture be used for
agricultural crop production.
 Gericke created a sensation by growing tomato vines twenty-five feet
(7.5 metres) high in his back yard in mineral nutrient solutions rather
than soil.
 In 1940, Gericke published the book, Complete Guide to Soil less
Gardening.
 In recent decades, NASA has done extensive hydroponic research for
its Controlled Ecological Life Support System (CELSS).
 Hydroponics intended to take place on Mars are using LED lighting to
grow in a different color spectrum with much less heat.
 Ray Wheeler, a plant physiologist at Kennedy Space Center’s Space
Life Science Lab, believes that hydroponics will create advances
within space travel. He terms this as a bio regenerative life support
system. 9AISSMS COE PUNE

19.  These gardens produce the healthiest crops with high
yields and are consistently reliable; gardening is clean
and extremely easy, requiring very little effort.
 Here nutrients are fed directly to the roots, as a result
plants grow faster with smaller roots, plants may be
grown closer, and only 1/5th of overall space and 1/20th
of total water is needed to grow plants under soil-less
culture in comparison to soil-based culture.
 There is no chance of soil-borne insect pest, disease
attack or weed infestation too.
 Overall soil-less culture provides efficient nutrient
regulation, higher density planting, and leading to
increased yield per acre along with better quality of the
produce.
 It is also effective for the regions of the World having
scarcity of arable or fertile land for agriculture.

21.  Application on commercial scale
requires technical knowledge and
high initial investment, though
returns are high.
Considering the high cost, the soil-
less culture is limited to high value
crops.
Great care is required with respect
to plant health control. Finally
energy inputs are necessary to run
the system

22. FUTURE SCOPE OF
HYDROPONIC TECHNOLOGY
22AISSMS COE PUNE

23.  Hydroponics is the fastest growing sector of agriculture,
and it could very well dominate food production in the
future.
 As population increases and arable land declines due to
poor land management, people will turn to new
technologies like hydroponics and aero ponics to create
additional channels of crop production.
 Hydroponics has the ability to feed millions in areas of
Africa and Asia, where both water and crops are scarce.
 Hydroponics also will be important to the future of the
space program.
 Hydroponic offers the potential for a larger variety of
food, and it provides a biological aspect, called a bio-
regenerative life support system

26.  Flavorful Hydroponics located in Pyalong,
is a tomato producer that has been in
operation for 14 years.
 The business consists of two 8,000
square metre greenhouses and produces
about 450,000 kg of tomatoes per year.
 Flavorful Hydroponics was successful in
gaining a $17,600 capital funding grant
through the Smarter Resources, Smarter
Business program to upgrade the climate
control system for their two greenhouses
including command station, display and
sensors, and associated software.
 The system was installed in August 2013.26AISSMS COE PUNE

28. CONCLUSION
28AISSMS COE PUNE

29.  The industry is expected to grow
exponentially also in future, as conditions of
soil growing is becoming difficult.
 Specially, in a country like India , where
urban concrete conglomerate is growing each
day , there is no option but adopting soil-less
culture to help improve the yield and quality
of the produce so that we can ensure food
security of our country.
 However, Government intervention and
Research Institute interest can propel the use
of this technology
