The document discusses hydroponics, a soil-less farming method that utilizes nutrient-rich water, allowing for faster plant growth and higher yields. It covers the history, various hydroponic systems, advantages and disadvantages, success stories from India and Australia, and the future potential of hydroponics in addressing food scarcity and environmental challenges. As urban space becomes limited and arable land declines, hydroponics is positioned to play a critical role in sustainable agriculture and food production.

2. HISTORY OF HYDROPONICS
• The process of hydroponic growing in our ocean goes back to about
the time earth was created.
• Many different civilizations have utilized hydroponic growing
techniques throughout history.
• Egyptian hieroglyphic records date back several hundred years B.C.
describe the growing of plants in water.
• Floating gardens of the Aztecs of Mexico
• Hanging gardens of Babylon, somewhere in (Iraq)

HISTORY OF HYDROPONICS

4. INTRODUCTION TO HYDROPONICS
What is Hydroponics?
Hydroponics is a method of growing plants without soil, using nutrient-
rich water instead. This allows for precise control over the growing
conditions, resulting in faster growth, higher yields, and better quality
produce. Hydroponics is becoming increasingly popular in agriculture,
particularly in urban areas where space is limited.
Stemming from the Greek words “hydro” (water) and “ponos” (labour),
hydroponics literally means “water working”.
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

5. HYDROPONIC SYSTEMS
• DEEP WATER CULTURE (DWC): In a DWC system, plants are
suspended in a nutrient-rich solution with their roots submerged
in the water. An air pump is used to oxygenate the water and
provide necessary nutrients to the plants.
• NUTRIENT FILM TECHNIQUE (NFT): In an NFT system, a thin film of
nutrient-rich water is circulated over the roots of the plants. The
roots are exposed to the air, allowing for optimal oxygenation.
This system is ideal for growing smaller plants with shallow root
systems.
• AEROPONICS: In an aeroponic system, the plants are suspended in
air and their roots are misted with a nutrient solution. This system
uses less water and nutrients than other systems, making it a
more sustainable option.

6. • WICK SYSTEM: A passive hydroponic system that
uses a wick to deliver nutrients to plants. Plants are
settled in growing media on a tray that sits on top of
a reservoir. Water and nutrients stream up the wick
and immerse the growing media around the root
systems of the plants. These wicks can be made of
fabric as basic as rope, string, or felt.
• DRIP SYSTEM: A hydroponic system that delivers
nutrient solution to plants through a drip emitter.

7. ADVANTAGES OF HYDROPONICS
• 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.

8. DISADVANTAGES OF HYDROPONICS
• 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.
• Reliance On Constant Power Supply/System
• Great care is required with respect to plant health
control.
• Susceptibility to Waterborne Diseases

9. SUCCESS STORIES
• In Hyderabad, Telangana, Harishchandra Reddy is a
successful hydroponic farmer.
• He has always wanted to create his own hydroponic
farm since then. So, he studied hydroponics and other
advanced agricultural technologies for six months while
raising the capital needed to establish the farm.
• He was aware that the first investment would be
significant, so he took his time gathering the money he
needs from various sources.
• Following that, he immediately began establishing his
hydroponics farm and began earning a huge sum of
money which is upto 300 crores per year.

10. SUCCESS STORIES
• Flavorful Hydroponics located in Pyalong (Australia), 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.

11. FUTURE SCOPES OF HYDROPONICS
• 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 aeroponics 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

12. THE FUTURE OF HYDROPONICS IS BRIGHT, WITH ADVANCEMENTS IN TECHNOLOGY AND
SUSTAINABILITY LEADING THE WAY.
As traditional agriculture faces challenges such as climate change and resource depletion, hydroponics
offers a promising solution for efficient and eco-friendly food production.
